I am all for giving the user a feetback what actions are lossless and what are lossy. The best place to archive that is in my opinion the digikam handbook (there allready are some infos about, but this might be extended). 

A second good place from my point of view is the "filter" section in the save dialog. There you currently can choose jpg, png, etc. as image formates. When you add a little(!) more information for each entry, like "PNG (Recommended)" or "JPG (Atention: Lossy)" then this might help some users find the right decission. For further questions a "help" butoon would be great that brings the curious user to the appropriate section of the handbook.

I don't like the idea of a warning message, cause this might just get "in the way" of most users. I am not sure about "save/export" separation cause I'd say most people do not realy know the difference. It's even more difficult for apps like digikam that have not a real default file format (jpg, png, tiff?).So I like the idea to use save as for all the image file formats and export for other kinds of storing pictures (like html export, flicr). Thats perfectly clear to me.

When this ideas get some possitive feetback I can review the handbook sections whis regard to this problem and write up a section about file formats and how they are handled with digikam (the secrion that should come up with the "help" button of the save dialogue).
