At the moment there are two image formats supported in Prof-UIS: bmp and png. There is a CExtBitmap class, written from scratch, which supports 32-bit bitmaps (loading, saving, and serialization) and is 100% supported even on Windows 9x/NT4. There is another class, CExtBitmapSkin, which is derived from CExtBitmap and supports 32-bit png images. CExtBitmapSkin is implemented using the well known and free LibPNG and ZLib libraries.
It would not be a problem to use other libraries for reading GIF images but we are using mostly 32-bit images with alpha channel and lossless formats. So other formats have been considered redundant so far.

There’s a class called CImage, a shared class of MFC and ATL. It can load gif file and has HBITMAP member variable, so you can use it instead of CBitmap. If some function expects a pointer to a CBitmap object, use CBitmap::FromHandle, pass it your CImage HBITMAP, and use the returned CBitmap*:
CImage image;
CBitmap* pBitmap = CBitmap::FromHandle(image.m_hBitmap);
In ProfStudio sample you can see the code needed to make a splash screen.
