Initially, I've used libpng for loading images.
But it is compatible only with some particular version of 
libpng.so
API version is passed somwhere in calls, and doesn't work with 
updated library.
I've tried to find some replacement for it, and found FreeImage 
(there was Derelict suport for it, and it was used in some D 
projects).
Probably, it makes sense to move to SDL_image. But it looks like 
it requires SDL as dependency.
Does it work ok on linux?
Let me check imlib2 as well.
