Php/ local server problem?

So I am running a local Apache2 server for testing my php/flash files
and have run into a problem
I am working with a dynamic imageviewer dev. by Vman her on the forums
and everything works until I try to remove images or change folder and
file names that are being called … flash and php keep trying to find the old
files and file names … So is there some kind of local cache problem?
By the way I have no clue what Im doing with this stuff , I am just trying
my best to extend my flash work so any help is greatly appreciated !

Thanks in advance ,
