Thanks for your answers, Adrian.

I've got a few questions: - Why is this warning? This is because TIFF images are currently set to be not includable in the Registry. 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. - Isn't there something incorrect if you indicate GIF or JPEG as object type when the object is actually a IOCA object and not a GIF or JPEG file?

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