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

[Daniel Fenn]

Don't quote me on this but I think piwigo stores thumbnail on the file system and not database.

Probably a stupid question, but... if piwigo stores its thumbnails in a 
database in a format that nobody uses, including browsers AND I see online the 
thumbnails being jpg, which makes sense since otherwise they would be useless, 
wouldn't that mean that in the piwigo code somewhere there's a conversion? 
And as I see this code on github it should be there somewhere? 

Not a piwigo user or anything, just wondering?
