A little trouble renaming and repositioning photos

I must learn how to rename and reposition photos.
I forgot and used Safari to upload, and we should be using Firefox.
But was able to do this, convoluted, but successful.
The problem was that my profile photo was covered up with the regular photo.
Firefox has put it correct, the profile photo is floating on the page.
Hey, I am learning, and this is one nice, really nice blogging site.
