I understand the directions and all its just for some reason i can never get it to work. The sims keep painting the old snapshot i took and not the new painting/ art i edited and saved for them to do instead.
Silly question perhaps, but are you putting the new image into Downloads? If so, it doesn't belong there.
You must either delete the existing Snapshot.bmp image and replace it with the new one or else overwrite it with the new image. And the new image must be named eactly as the existing one - if the existing one is Snapshot.bmp (with a capital S) the new one must be named exactly that way.
Have never had a prob doing this. Perhaps this procedure will help you:
Open your graphics editor and do your resizing/cropping/whatever of your preferred image.
When that is done, use 'Save As' function and make sure the file type is set to bmp
Navigate to the Storytelling folder in My Documents-EA Games-Sims 2 and choose the Snapshot.bmp file. This will overwrite the existing file upon completion of the 'Save As.'
If, for whatever reason, your particular graphics editor happens to save the file with a .BMP extension, change that to all lower case.
