Hey, sorry. This is actually about your theme. I use this theme for my blog but I have no idea how to change the background. Could you help me, please?

I sure can as far as my knowledge goes.

So you go to your dash and to ‘Edit theme’ and then left in ‘Edit HTML’

Then you go to the line 157 where for me it says: 

background: url(http://40.media.tumblr.com/35f4aacfbe883dd7fd44b515d8e82d42/tumblr_myztvpKbu61t96e40o1_1280.jpg) #8f9595 repeat-x fixed;

and the url in the brackets obvs is the url to the pic I wanted to have back there

and that’s basically it… if it isn’t line 157 for you, try searching (cog on the top left of the ‘Edit HTML’ page -> select ‘Find and replace’) for ‘background’ and look for a place where it seems likely for you to put an url. If I remember correctly I literally just replaced the original url adress with the one I wanted it to have

… did that shed light on anything or was that too confusing?
