change a swf file’s infinite loop into single loop

I have created a flash photo gallery with the help of a paogram. The swf loops infinitely and i wish to change this behaviour to loop = zero but this setting is nt available in the program. can this be achieved in any other way?
Answer #1
Can’t you just decompile the swf file with adobe flash?
If not, try a proper flash decompiler? Then recompile it with the corrected setting using adobe flash?
