Pics are restricted to a screen size of 400 pixels by 400 pixels - if you open the pics up in a photo editor it should show you the dimension and you should also be able to resize them to fit.
This restriction has nothing to do with the file size (in bytes)...just the pic height and width in pixels.
Thanks
Yeah, I do them myself. My wife doesn't understand why I do so many. I just like to do them. I need to get an airbrush though. Can't do a whole lot with spray cans.
