How to upload an image from your computer:
Step 5) Upload your picture to an image hosting website from your computer. Here are 2 you can use (no registration required): https://tinypic.com/ or https://imgur.com/
6) After you have uploaded the image you will see multiple links near the image. Copy the link that is in the Direct Link for Layouts box or the BBCode (message boards & forums) box. Head over to the contest thread or the thread you are going to post the image in and paste the link you copied into the comment box where you normally post your text in the thread.
7) If you copied the BBCode (message boards & forums) then you are done, just press "post reply". If you copied the Direct Link for Layouts then be sure to add these as a prefix/suffix to the link: [img][/img]
So it should actually look like this while you're editing
