match one of three possible substrings?

It doesn't look like this is possible, but i'm often wrong =o)
In Bash you can use *.{png,jpg,gif} to match any of 3 possible filename extensions.
Can this be done in Lua?
What I have right now works, but it seems terribly redundant:

Code:
for i=1,table.getn(allfiles) do
if string.find(allfiles[i],"%.png$") or string.find(allfiles[i],"%.jpg$") or string.find(allfiles[i],"%.gif$") then
some_commands
end
end


Thanks for reading.
