If you already have them as a binary blob, then Fl_JPEG_Image is probably not what you want (since it is meant for loading jpeg files from disk etc.) Instead, just decompress the blob into RAM somewhere using the normal jpeg functions, then use that decompressed image in RAM to form an Fl_Image or even just display the data directly in an Fl_Box or something. There's a how-to that touches *some* of this here: http://www.fltk.org/articles.php?L468 It doesn't cover decompressing the binary blob into RAM, but that's a fairly common jpeg lib thing so a quick google will surely turn something useful up. In fact, don't the jpeg docs in the lib describe doing that? I can't remember now, it is so long since I read 'em... -- Ian SELEX Sensors and Airborne Systems Limited Registered Office: Sigma House, Christopher Martin Road, Basildon, Essex SS14 3EL A company registered in England & Wales.
