What format do the pictures have to be in?

[PspPortalMaster]

I have just drawn all my pictures only to find they are in the wrong format(there was a red cross in the top corner) does this mean you need flash or are the pictures in the wrong format?

I suppose that you are talking about psp games, since your previous post was connected to them.

Here is a thread that is about picture problems in psp games, maybe it will help you:
