Posting photos

[bbg]

I sell some parts on occasion on ebay and it is very easy to put the photos on. I just can't seem to figure out how though to post them anywhere else. Can any of you folks tell me an easy way to post them? I am very computer illiterate and if it were not for my daughter who is married and moved out now I couldn't do what I do. Please help out if you can. I just tried at the end of this post to ad a photo and I may have stumbled upon it but it came up and said it could not proceed because it was too big. How do you fix that?
