Firstly, cd images are usually bigger than the actual cd as they contain more info than just whats on the cd.
Secondly, if u have a clone cd compatible image the its the .img file size that you need to worry about. The .cue size and the.ccd size should be very small. and you can use either the .ccd or .cue file to burn the .img file.
Perhaps you've misread the size of the .cue and .ccd file. If thats the correct size delete and start again as you've done something drastically wrong
