Thanks Seacoast! Yeah that seems to be the best way to fix the problem.
Thanks. This is perfect.
Just sucks because there was a point when there was a button that said something like “keep image size”, or something to that effect.
This picture rotator looks pretty nifty, and I’ll probably just go ahead and adapt my Header-image-making to the minimum limits imposed by the themes. This will make things easier.
Thanks so much Esmi!
