seems that symlinks for gif files instead of actual gif files don't work when set up as interwiki icons.
The idea is to have several URL sharing the same icon. So, instead of having several copies of the same icon, have only one so when one wants to change them, it only changes one. The interwiki link that has the actual file with its name, has the icon set up correctly. The others, which have symlinks, do not.
3 lines from interwiki.conf
ls -l of /lib/images/interwiki/

If you don't consider this a bug, please consider it a feature request. Thanks
