How to post pictures to forum?

[blackpython99]

Hello there! I'm new to the forum and I have a few queen ants that I have recently caught that I need help identifying. I was wondering how to post a picture to this forum to help with that. I see others post URL's that link to pages that they have posted their pics to. Thanks for the help!
