Old Gobbler has a sticky regarding using Tinypic. When I launched Tinypic they say they've shut down. I use Imgur for posting. After you upload a photo choose "Large Thumbnail" size first then copy the BBCode. After you paste it in your forum post, do a Preview before you post. I think you'll like it. Personally, I dislike looking at photos whereas I have to use the scroll bars because the picture is huge. Check it out.
P.S. "Huge Thumbnail" may work for you as well...do a preview on both prior to posting. For aesthetics post the picture whereas scrollbars aren't required for a 1080P screen, which is what most folks use.
