I'm not very tech savvy but I will help if I can. I upload my photos to photobucket (free), then right click the photo, select copy image URL. Now on the forum start your post and click above the smiley

on the insert image icon, [img] [img] will pop up, I hit the space bar a couple times to give myself some room between the brackets, now in the space I just made, right click, select paste. before posting hit preview to see if it worked. A few other ways to get it done but this works for me.
