Vaping Biker

You're a hero! Thanks! For some reason I didn't look up on the top bar. Thanks very much!

Hi everyone, I'm finally getting to play with the theme designer on a mac - something I'm unnaturally excited about - anyway, obviously I can upload a background with a 'landscape' image by turning it 90 degrees before upload, but I cannot for the life of me see where I can can adjust any of the screen info into a landscape format. I'm pretty sure the vapedroids have it, and I've seen another on here, but I've had a search around the forum with no luck. Can anyone help? Cheers all
