Alaska uses several separate multiimage controls for the home screen and if you simply point them to your fanart folders then you certainly see the effect they have on the cpu.

If the images are resized to fit the dimension used in the multiimage controls then you don't notice anything when they all change image.

I would suggest that the running of the script for these purposes be handled by the skin with the appropriate dimensions set by the skinner. All the user need do is point it to the folder containing the images to be resized and then the output folder, which in turn would be set as a skin image path.

Thanks.

EDIT Maybe a completely separate script would be better suited for this?

That would make it very skin specific and a user needs several different folders when switching skins. Maybe looking for a compromise?
Find some acceptable image size all skins can use. Lets take fanart 1920x1080 and shrink it to 640x360 or something. This would drasticly decrease images filesize (factor 9 or something like that) and still be usuable by many skins.
