Sorry, this was no properly written question. I can see that it is
marked as such, but why do you consider this a reason to issue a warning?
If it's technically impossible to use the image a includable resource,
then it simply has to be inlined. I don't see a reason to confuse the
user with this.

Sounds promising.

Probably an inconvenience but a document with a TIFF logo on every page
will profit quite a bit from the TIFF being includable.

If you put JAI ImageIO Tools in the classpath, this will work fine.
