GIF stored in the database and CR 9

I'm trying to display pictures stored in the database (SQL Server 2000 image column) in the report. JPGs are coming back fine, but GIFs are not. No errors, nothing.
I can't find anything on the businessobjects web site about not supporting GIFs... site is well known for how hard is to find information on it, but this time I can't find anything. Only one article about supported forms for repository, and there is no GIF format there.
Insert Picture is also ignoring GIF files, just JPG, TIFF, PNG...
What's going on?

** UPDATE **
GIF format is officialy "not fully" supported; for database retrieval, for logo retrieval in XI from file system, use either JPG or PNG, and forget .GIF. For embeded pictures in report, you can use GIF as OLE objects in version 9...
