posting photo to profile

I give up . . .
It's 3:00 am. I wrote a blog; I added all my classmates links to my blog (finally!). And, although I can get a photo into a post, I can't get it into my profile (the URL that is given to the photo upon uploading is too long for the template—they only allow 68 characters). Does anyone have any tips on how to handle this? How can you rename your URL or extend the allowable number of characters?
