For some reason, only certain image file formats show up as previews on our Confluence pages. .jpg, and .png, seem to work, but not .ai. And .psd only sketchily (i.e. for whatever reason not when saved into .psd format from the original .ai format). How do I solve this? I particularly need to show preview images in those two formats.
I have checked that the Confluence files add-on is enabled, and it is.
