Question: what size/resolution does an image need to be in order to use it as the "body background image"? I am finding the images that I'm using to look extremely stretched and not at the right dimensions. Also, for the logo area, how can I get rid of the white space around my logo? My Mac computer recognizes JPEG2000 which allows me to save with transparency and save only the logo, but the Themia theme does not support that file size. I would like to use the logo as transparent so it goes over the body background image nicely. Thanks.
