Dissolve image transition effect

I'm doing an application that requires displaying images in the background (each one is displayed for 15 second).

The problem I'm facing is that when switching from one image to another, it must have the dissolve transition effect (dissolve the current image and in the same time display the new one gradually)...

Anyone knows any algorithm or source code (in any languages, no need java) for doing that?

Thanks for viewing...
