I'm not the best at this and always struggle. Open your photo gallery on this site. This site will not accept max resolution picture, so you have to use a photo program to reduce the resolution first. Once you get that done it is fairly easy to copy them. Look in the all Cobra talk area. I think there is a sticky that explains this much better than me.
Once it is in your photo gallery, anyone can see it. There is a way to link it in your post, but it always takes me a half dozen attempts to do it.
