Feature Proposal: Easier inserting and resizing of images


I am probably the only person in my company who is able to insert an image into a document. Unfortunately all the other users (engineers, mechanics, secretaries and other computer-literate people) have an immense trouble with inserting images in Twiki articles. I think many would agree that this can be made more user-friendly. A bit like (ugh) MS Office inserts pictures into documents, presentations, etc.

Description and Documentation

When inserting an image from the Twiki WYSIWIG editor, a pop-up wizard could appear as follows:

  1. Browse for picture and select it;
  2. Upload the file to the Twiki server;
  3. Show the size and resolution of the selected file;
  4. Specify to what size the picture should be adjusted, either:
    • Default (a specific default pixel size, e.g. 72 dpi)
    • or choose from a selection of sizes;
    • or original size (this should be < 500 kB I think).
  5. Choose wether in addition to inserting the resized file the original file should be attached to the article;
  6. The file is then resized and inserted, and also the original attached.



WhatDoesItAffect: Performance, Usability

We added this functionality to our internal wordpress blog. What we found out is that users just upload the photos from their camera, huge 5 Megapixels or more. They have no idea it is a big one. So we configured the plugin http://www.soldesignco.com/wordpress-imaxwidth.html (*) to resize the image to 1024px width max automatically with no options. So we only do steps 1,2 & 6, the rest is automatically done to avoid confusing users. If they really want to upload high-resolution images, they will have to contact us, and we will advise them not to store them on the blog anyways, but on dedicated servers with big storage, and mirrored in various countries

I'd advise doing the same for TWiki. just force resizing (and jpeg optimization), do not provide options.

(*) with some enhancements

Thanks for the info. I forgot to mention that all the steps I described should be in the Twiki WYSIWIG editor.
