Bob. Are you hosting your image on TM-IMG? If so, I'm afraid it won't work, even if your file has a .jpg extension the TM-IMG site changes it to .jpeg
You can change the "smiley face" by clicking on it in the top-right corner of the site, next to your name.
Edit: I was going to add a link to where this was discussed recently but I see you seem to have posted the answer there yourself Bob...
