When browsing a category containing images, only the first 20 characters of the image name are shown. However the end of the image name is particularly useful as it containes 1) the file type (png, svg, jpg, etc.), and 2) any extension like "-fr.svg" for diagrams in French or a number for a sequence of images.
Therefore it would be useful to show the end of the image as well as the beginning.
Maybe the image name could be shown on two lines instead of one, or maybe the last 6-7 characters could always be shown, with "..." in between, if the filename is too long to fit?
