[digiKam-users] Thumbnails are in Progessive Graphics File (PGF)

After digging around a bit, I think I have the answer to the question about
how the thumbnails are stored, which is PGF:


Unfortunately, I cannot for the life of me find something in PHP that will
convert from PGF to JPEG or PNG.

Not surprisingly, it takes up a lot of space, but is wasted bandwidth for
using a remote database.

Any suggestions on how to convert it?
