I know that I should know this by now, but I don't. I need help uploading photos, or a link to the thread about uploading photos. Any help would be greatly appreciated, thanks in advance!

Upload the photo that you want to post here, to Photobucket
Then all you have to do is copy and paste the IMG code on here.
You can also use the attachment button but it wont actually show the photo, people have to open it to see it. I have seen some people say that they have to post photos from a computer but i have successfully post from my phone both ways so it must depend on what device you have.

Thanks Jacob!
