RE: match one of three possible substrings?

Thanks for the pointers.
It still seems to be overkill to first match all similar extensions, including ppf, ppg, pnf, png, pig, pif, jng, jif, ...
...and then check for the three desired extensions. The same result could be obtained by grabbing the filename extension regardless of what it is, if you are then simply going to compare it with ".png", ".jpg" and ".gif"

I'm guessing this is not going to be as straightforward as using "typical" regular expressions, but i still get the feeling that it could be made simpler than it is.

I'll look at match/gmatch to see what can be done there.
