I Give Up!

It's 3:00 a.m. . .
OK. I wrote a blog. I added links to my classmates blogs on my blog site. I want to add a photo to my profile. Not sure what I'm doing, I downloaded "Hello" but saw later that I could just upload the file from my desktop (I was following help on blogger but then re-read Carleen's instructions). I got a photo onto the site as a post, somehow (!), but can't seem to copy and paste the URL to put it in my profile (I get an error message that says the URL has more than the alotted 68 characters). Of course, the URL was given to the photo as I uploaded it from my desktop, so how in the heck do I change it? Any tips would be welcome!
