Well bummer...
"TinyPic will be ending its image hosting service in 2019 because we can no longer support a free service that derives 100% of its revenue from ever declining on-site ad revenues.
While you may continue to host images from our site until further notice, we encourage you to consider selecting one of the premium plans offered by our sister site, Photobucket.
Thanks for using TinyPic for your hosting needs over the years. We apologize that we can no longer continue providing this service, but Photobucket is a great option going forward."
Well..that figures
Try Imgur...it's what I use. Very simple to use. What I do is select the pic I want to post then choose BBCode and Large Thumbnail size. Posts perfectly...or you can select a pic and edit it to your preferences.
PS Select the large thumbnail prior to telling it to copy the BBCode.
