Ok, so im creating a rpg and need help with how i should save the textures so it doesnt affect the game size or speed, much. So far i have about 50 textures made, they are all in the same folder and saved as either bmp or png, now do i compress it or something. And can someone explain to me how compression works. Thanks

bmp is simple & compatible format,
but it`s packing and internal format support is poor.

png is good format and it`s packing capapility is good.

Easyest way to make clean paggage of images is to use pkzip format,
and load stuff out from it with some library.

(fast google with "pkzip library c++")

Best (and hardests) formats of CG.

OpenEXR: http://en.wikipedia.org/wiki/OpenEXR
JPEG2000 http://en.wikipedia.org/wiki/JPEG_2000

Ps. I suggest just using PNG with pkzip packing.

Thanks a bunch, i'll give it a try.
