I'm Back & Looking for blogging help

My lack of computer literacy had me a bit discouraged for awhile, but now I'm determined to improve & maintain my blog. I got a new camera for Christmas, but my ancient computer can't upload the pics from it, so I'll have to continue to use my old camera 'til I can afford a new computer. My biggest problem right now & the reason I haven't signed up to watch a lot of blogs I'd like to is because when I do, it doesn't include my avatar & lists my name as my e-mail instead of my blog name. Can anyone tell me why this happens.
Thanks,
Rick
