If using photobucket... I've taken screen shots of photobucket and then uploaded them to photobucket to link them to here as an attempt to show how to use photobucket.
After you've uploaded. Second from the left link, at the bottom of the posted image. This is the typical "share" icon.
Then click copy link.
Copy the DIRECT LINK to the image. None other.
If the image icon on our website doesn't work for you on your computer or phone (HTML issue?), manually type before pasting the link then / afterwords.
If need be I'll do the same but with the desktop view so the screen is exactly as a desktop computer.
