I am opening a shop on CafePress and I would like to place a custom banner in my blog advertising the shop. I know I can place the image in a post and link it to the shop, but I would like to put it in the sidebar so it will always be visible. AFAIK, this could only be done w/ the text widget, using HTML.
So how would I make a banner with my own image that would link to my shop?
These are the type of banners i'm talking about, though I wouldn't need animation:
The blog I need help with is throughagreenlens.com.
