I missed this bit from the website:
When using FreeImage in your open source or commercial application,
you are REQUIRED to :
distribute the license (GNU GPL or FIPL) you choosed with your
application (i.e. the TXT file)
provide a suitable acknowledgement, either in the program's "About"
box or in the user's manual (or both), for example :

This software uses the FreeImage open source image library. See for details.
FreeImage is used under the (GNU GPL or FIPL), version (license version)."

Apparently they want you to mention that you are using their library
which is not something we do in Wine (as far as I know) for anything
else. (If we were using the GPL version, I'm not sure if the GPL even
requires to such an advertising clause which I believe it doesn't)
