Sorry, I'm a newbie and this is probably a stupid question. I just got my first blog up and running in January, I am using twenty eleven, but I dislike the infinite scrolling they just switched to. So I want to switch to a new theme - I know how to do that, but when I tried, I noticed, though I still have my whole media library intact, I don't see an option for using those already cropped images for my custom header. It seems I have to download them all again from my computer and re-crop again? If you know the answer to that - and anything else I might need to keep in mind when switching themes, please let me know. I know I could spend a lot of time looking this up - but it seems it's already going to take some extra time just to set stuff up with a new theme, so if anyone has fast tips/pointers, I would really appreciate it. I switched my theme back to twenty eleven for now, becuase once I switched to a different one my blog didn't look right, and I didn't have time to fix it all up right now.
Thanks for your help :-)
The blog I need help with is rebelsprite.wordpress.com.
