[RESOLVED] Filename for snapshots and titles?

What filename does GameEx look for when searching for the title and snapshot files?

The reason I ask is this:

I have several games setup from a "Other Emulated Games" emulator, with the actual gamestart.exe files located in various folders but with links to all of them located in the designated ROM folder for that "emulator".  The links have more readable names than the gamestart.exe files have (e.g. "Pole Position" vs. "polepos.exe").  

I then name my title and snapshot pictures as [readable game name].png.  (For example, both the title and the snapshot would be called "Pole Position.png" in their respective folders.

The problem that I have is that it GameEx is not finding my title and snapshot pictures--or rather, for some games it finds the file and then for others it doesn't.

Can anyone provide some insight?

Thanks!
