I cant even open them or i would have tried the suggestion ratter gave.
Ive tried opening them in photoshop but no luck there either.
This is the message i'm getting

which is suppose is self explanatory.
They are specifically Windows Bitmap files so that may be something. Ive never come across this sort of file before and i suspect it is the individual files that are to blame and not my mac (or my incompetence).
