You'll see there are a couple of new tabs at the top of my blog, under my header. The one on the right, that says "free backgrounds" will take you here.
I've also included instructions for uploading. You can maybe use them for other blog formats, but since I don't use any others, I just don't know. If anyone tries it with something other than Blogger, or other than the Watermark template for Blogger, let me know if it works!
Update: I have decided upon
New blog: oldcrowbackgrounds.blogspot.com
Twice the exposure, can't be all bad, right? Unless it's 95 degrees out and you don't have your backside covered, then...well...
