Sure ! You can post links with no problem. If you use "edit" when you're done with your question, you can insert small pictures. Too big and it messes the site up. Another way is to ask your question and put your picture in the first answer. Once you're here a while, I'll teach you to put gifs and images in your questions. It's a little work but I have it down to an art.
have you the admins or people who work on this website have you ever thought about adding the ability to paste links on questions and/or photos?
