Answers to some commonly experienced problems
During the last week I noticed that questions and queries about images in presentations, problems with them and how to use them poped up again and again. I will try and address some of them.
- The image gets too big or distorted in a slide
- The short explanation is - by default the image is scaled to fill an area covering the most of a slide, the proportions of that area are 4x3. Why, you whould ask? Well, the reason is that we have several views, first the "small view", which is designed to work in browsers which lack support for javascript or it was disabled. In this view we have the slide itself, an abstract or speaker notes, comments, navigation elements. We can't make the slides too big because the rest of the content on that page will be unreadable. The text in the slides still has to be readable. Second we have the "full screen view". The content is scaled to fill the whole screen. Thirdly we have the "printer friendly view". It collates the whole presentation, from the current slide down, on one page and istyled appropriately for printers
- I have problems with previously uploaded images
- We have changed some of the server settings to increase the performance, unfortunately it resulted in a change of some of the system paths as well. Most of the problems should be resolved now, but if you still experience any, please don't hesitate to post your problem in this forum. Apologies for any inconvenience that might have caused.
- I was asked to download a file instead of seeing the webpage
- In order to increase the speed of the website we installed acceleration software. This resulted in about 5 minute downtime. Sorry for the inconvenience. The website is working fine now
- The wysiwyg editor is not very user friendly. It produces strange output.
- The website uses an editor called TinyMCE, it was one of the better opensource editors prodicing (nearly) clean xhtml. We have a problem. We want to provide familiar environment, while producing standards compatible, accessible and user-friendly website. The website can and should be improved. In hindsight the editor and producing html directly might not have been the best choice. Any suggestions, comments and recommendations are welcome, please post them as comments here. To find out more how to use the current editor, please have a look at the website user guide.

Vlado,
The user of this presentation, http://conference.iproms.org/node/185, write all the text in the "Excerpt" body, and all 20 slides are like this, in rest is ok(point of view of the weight) and connections.

Yes, this was caused by some of the pages in the presentation not being
selected as slides, i.e Slide: none. I've corrected this. And I'm creating an example presentation highlighting the problem. I'll add it to the website guide.
I've created a short demo for this behaviour.
hmm, that presentation is peculiar. Kim was trying to create an image based presenation. But the sources of the images point to his C: hard-drive. I've sent him an email. So hopefully he'll be fine.
Vlado,
I pass through almoust all the slides(uploaded) i made 8 categories of "defects"
Liviu
1. ppt slides in book pages
http://conference.iproms.org/presentation/222
2. Slides with and without H1(heading1) for titles
http://conference.iproms.org/node/144
http://conference.iproms.org/presentation/145
http://conference.iproms.org/presentation/117 - just for conclusions slide
http://conference.iproms.org/presentation/171 - slide four look's different
3. Formatting problems
http://conference.iproms.org/node/189 - 3rd page
4. At the end of slides with image there is the </div.........> comment - has to be canceled because the title of the next slide will appear smaller.
http://conference.iproms.org/presentation/116
http://conference.iproms.org/presentation/159
http://conference.iproms.org/presentation/152 - this is also without H1 setting, and see the conclusion slide
http://conference.iproms.org/presentation/213
http://conference.iproms.org/presentation/164
http://conference.iproms.org/presentation/139 - take a look even @ the first page
http://conference.iproms.org/presentation/207
http://conference.iproms.org/presentation/223
5. writting error
http://conference.iproms.org/presentation/134 - Future work at place of futire - last slide last paragraph
http://conference.iproms.org/presentation/490 - Comparison at place of Comaprison - last slide, and table border=0 in slide 6 and slide 7, and first page(a page with Paper Title and authors)
6. Image or text in background
http://conference.iproms.org/presentation/151
http://conference.iproms.org/presentation/132
http://conference.iproms.org/presentation/225
7. Excerpt body -
http://conference.iproms.org/node/752/edit - Text 1st slide written in excerpt body, also H1 is not set-up corect in different slides, the slide type, weight and parent setting are not inserted in all the slides.
8. I don't know where to put this one -
http://conference.iproms.org/presentation/522

Vlado,
the same paper was insert twice
http://conference.iproms.org/node/1579 and http://conference.iproms.org/node/609 to me are the same one???

1. ppt slides in book pages

Well, I wouldn't consider it a defect, although it goes against some of the benefits an online conference like this one can bring to the authors of papers
- exposure and how "googleable" is the paper and the presentation
- how accessible is the presentation, which reflects on not only the people with hearing disabilities, but on bots as well
- the reason we leave only semantic markup or meaningful markup elements is that this adds extra meta-data about the presentation or the abstract of the paper.
It is not good, but ultimately it's authors choice. I believe it is possible to present better the contents of the paper on the web in xhtml rather than in bitmaps.
There are other problems with that particular presentation, which are caused by what I believe is a bug either in the editor or the html filters. I'm investigating it and will report it to the authors upstream.
2. Slides with and without H1(heading1) for titles
http://conference.iproms.org/node/144
http://conference.iproms.org/presentation/145
http://conference.iproms.org/presentation/117 - just for conclusions slide
http://conference.iproms.org/presentation/171 - slide four look's different
Yes, it is adviseable to use Heading 1 (<H1>) for the titles of the slides. The title is positioned at the top of the slide in a header area. It is not a sin not to do that, but it breaks the common look of the slides and is eating space for the text.
3. Formatting problems
http://conference.iproms.org/node/189 - 3rd page
The beauty is in the eye of the beholder. But this demonstrates a typical problem with the current javascript wysiwyg editors. They don't produce valid xhtml. Unless we write a comletely new editor this is not to go away.
I will try and advise the presentation authors for how to repair such cases, as well as I will try to automate the cleanup process.
4. At the end of slides with image there is the </div.........> comment - has to be canceled because the title of the next slide will appear smaller.
http://conference.iproms.org/presentation/116
http://conference.iproms.org/presentation/159
This is a similar issue as the above. I will try to automatically clean it up. Or repair otherwise.
5. writting error
http://conference.iproms.org/presentation/134 - Future work at place of futire - last slide last paragraph
http://conference.iproms.org/presentation/490 - Comparison at place of Comaprison - last slide, and table border=0 in slide 6 and slide 7, and first page(a page with Paper Title and authors)
Spellchecker? Maybe in the future. I am as much culpable of this sin as anyone. We'll need gently to either ask the authors or just correct it. Whichever works better.
6. Image or text in background
http://conference.iproms.org/presentation/151
http://conference.iproms.org/presentation/132
http://conference.iproms.org/presentation/225
That is a consequence of leaving a Slide dropdown to <none>. I have created a demo highliting and explaining the problem.
7. Excerpt body -
http://conference.iproms.org/node/752/edit - Text 1st slide written in excerpt body, also H1 is not set-up corect in different slides, the slide type, weight and parent setting are not inserted in all the slides.
That is an editor bug. And at least at the moment the authors not only of this but the majority of javascript wysiwyg editors won't fix it. They don't want to overcomplicate their application. A possible solution will be automatic cleaning up of the html code on the server side.
8. I don't know where to put this one -
http://conference.iproms.org/presentation/522
It is just a part of the editorial process. They are still working on the presentation.
What happen to all the images in my presentation slides? Can you resolve the problem soon?
The images point to a path at your harddisk. I can only gueass that probably you have just pasted them form your windows explorer. To upload the images you need to use the website interface. Have a look at Working with Images and Creating a presentation.
I have tried to upload a first version of my video presentation but i did not succsed because this error came on screen "The selected file IPROMS_AE.wmv can not be attached to this post, because the disk quota of 10 MB has been reached." The video presentation that i have to upload are 5MB max.
I mention that i have to upload 3 presentations for the IPROMS conference.
What shall i do?
Thank you for your help!
