You can mount a file as a filesystem with the loop file system.
Go 

    losetup /dev/loop0 <your image file>

then just mount or whatever /loop0. (Up to loop7 is supported).

If you want to make a new file system in it, you need to create an image
file of some format first, eg with dd;

    dd if=/dev/zero of=<your file> bs=<size of file> count=1

then you can losetup it, then mkfs it or whatever else.



Hope this helps,
