Sorry, but this is impossible in general.

The reason is that most recent boot CDs use no-emulation boot and mark the boot 
"file" as 2048 bytes only.

The first 2048 bytes of the file contain code that pulls the rest of the file from 
disk and only this code knows the size.

What you can to is calling "isoinfo -i image -d" and check the results.
