I have checked the image location. Here it is (in order to keep the user details private I have removed the web address) .....
"http://www.THEusersW....com/image.gif" without the quote marks.
If I view the Selection Source in Firefox for this gif and look at the first line where the image is located the html code is .......
<p><img src="http://www.THEusersW...e.gif"><br><br>
I do not understand how this source can be entered when the site offers no facility to add img source code within the body of the text.
I have tried adding similar code in the body of my posting text but all it does is adds a link from it without inserting the image. I have to admit I have not posted the changes but just previewed the result.
Where forums allow a link it is possible to use the link facility to Photobucket and that inserts a picture within the posting. I could try using Photobucket as I have pictures there already, but having tried inserting text that links to a picture on my web site and that does not work either I cannot see how Photobucket will be of any help.
This same Classified Advertising site does however offer a separate facility to add 3 pictures, but as there are a countless number Classified Sites on the internet that do not offer image insertion facilities at all it would be helpful to know how this can be achieved.
