Hap,
You're making uploading photos from Photobucket and then displaying them in the TG messages more difficult than it is.
If you still have your Photobucket account, upload a photo from your computer that is no bigger than 600 pixels to your Photobucket album. When the photo shows up in your Photobucket album, hover your cursor over the photo. A little box pops up under the photo and it will list four codes under the photo. Just copy the "img" code. You do this my holding down the Ctrl key on your keyboard and then pressing the "C" key. That copies the code. You then type a message on TG and then to show the photo in the message, hold the Ctrl key down again and then press the "V" key. The code shows in the message. Hit the Preview button and the message shows up and it will also display the photo in the message. If you see the photo in the preview message, then hit the Add button and then your message with photo is on here for us to read and see. Of course, I'm assmuming you're running a Windows computer and not an Apple computer. Thing will be different on an Apple computer.
