Topic: Changing Arrows

Hello

I've purchased SimpleViewer Pro, and I want to modify the arrows that appear on the image, I don't want there to be any thumbnails, so it's just the arrows that appear on the actual imag ewhen you hover over. What are the guidelines? I've managed to change one of the other images, but the arrow appears all pixelated, and it looks awful. Please help, it'd be greatly appreciated.

Thanks a lot

Regards
