Can you recommend me some good JPEG libraries whose load functions will return a pointer to bits so I can display jpeg pictures via GDI? I need some small, compact jpeg library only to handle jpeg pictures (load/save).. I know few of them, few do not return pointer to bitmap bits, and few are so large..... Some recommendations?

DevIL might be what you're looking for.

Thanks for your recommendations. But I saw that its DLL is 800kb.. It is about 40 times larger than application I'm creating.

And, I think it is not just for JPEG - and that's probably why it is so big.

However, I need something like AllegroJPEG except that I can handle bitmaps with GDI...

All I need is - Jpeg-to-bitmap and vice versa.

You could scrounge for a way to convert JPEG to BMP directly, but using another lib would at least save you R&D time for something that is trivial and shouldn't bog you down early on in your project.

If you're particularly concerned about DLL/EXE sizes, consider using UPX to deflate them.
