Whoo!!! Sorry. I know this is supposed to be a help forum, but you guys aren't helping much (no offense),
No offense, but you're giving people absolutely zero information to work with -- we have no idea what images you're using, what your input routine looks like, how you're cycling through your frames, and how you update to screen, just to name some things.
'Problems' like this are absolutely impossible to help with unless you post some code that you are using, so people can see what it is you're trying to do, and possibly point out logic problems in your code.
