Adding pictures.....

I am SO slow to figure this stuff out. My students all have MySpaces and my daughter too, but this seems more 'mature'. no? Anyway, I think I finally understand how to do this - we'll see! I have to put my picture in the blog, then it'll have a URL so I can put it into my profile - I think! Here goes!!!
Hmmm...it's not working again....keeps saying 'error on page' when I press the picture icon...it did this before, then it worked and I added the pictures..I wrote down what it said to do, but now it's not doing it! Is it me??
