.IMG files

OK, Im sorta confused about the download I got when downloading chrono cross disk 2 0f 2. I had gotten the .CUE and .BIN files but there was no .IMG file that ISO's are supposed to have when running on an emulator, such as ePSXe, did I download the wrong file or is the file missing it's .IMG? or is disk 2 not the same as 1?
anyone have an answer for me it would very thankfull.

i belive the bin file is the same thing as the img file if not just check the file size i think the bigger one would be the correct game
