Animated GIFS can't be resized in Confluence

    • We collect Confluence feedback from various sources, and we evaluate what we've collected when planning our product roadmap. To understand how this piece of feedback will be reviewed, see our Implementation of New Features Policy.

      NOTE: This suggestion is for Confluence Server. Using Confluence Cloud? See the corresponding suggestion.

      Specific GIFS are not working properly in Confluence 5.1.x versions. In this case, when you try to re-size the GIF to the smallest size (thumbnail) it's not displayed in all browsers. I have attached the gif file in order to reproduce it.

      Steps to Reproduce

      1. Create a page
      2. Edit the Page
      3. Insert > Image (or Drag&Drop the GIF file)
      4. Re-size the image to the smallest size option:
      5. The image thumbnail is not displayed properly

      PS: If you try to open the same GIF in a new tab, Confluence will display an 'java.lang.ArrayIndexOutOfBoundsException'

            After upgrading to Confluence 5.3.4 I see that this is working now surprisingly.
            Tested using Firefox 39 and attaching the given gif to a page and changing its size shows the static (unanimated) image on the page. By clicking the thumbnail, it pops up the original sized image which is then animated. So we are all fine here.

            @jmasson A colleague of mine just ran into this issue (running Confluence 5.2.5 here). If it's not going to be supported then maybe at least the image-toolbar could have the resize-buttons disabled (greyed-out), so it's more explicit that this functionality is unsupported?

            I mean it doesn't make much sense to be able to tick the resizing of the image and this results in a "placeholder" icon which is certainly less than what the user would expect...

            You mentioned that there are specific tools you'd recommend that we use but didn't actually specify the tools. Could you please give some examples?

            This is true, it can't, but it's a tricker problem than it seems. A lot of image editing tools can't either!

            As a work around, there are specific tools for resizing animated gifs and 'd recommend using one of those then uploading it.
