i have photoshop and a friend of mine is in the pic.
It doesn't matter if a friend of yours is in the image.
If
you don't own the copyright to the image, it's still a violation of TPF rules to post it, rather than linking to it, simple as that.
Here's the deal.
Whoever made the image is the copyright owner. As the TPF rule states, if you can provide to TPF management, a written copy of permission from the copyright owner to use the image online, you will no longer be in violation of the rule once TPF management has that copy of the written permission in their hand.
Until then, you're violating the rule and the right thing to do is take the image down and linked to it.
TPF is a commercial venture and it's possible, though maybe not likely in this instance, they could be sued. That's why they have the rule, to protect themselves legally. They have the option to ban people from the forum who choose to ignore their rules.
Since you have Photoshop, you're all set. Youtube has a lot of how to Photoshop videos.
