The HTML tags are for showing html code as text.
If you want to display pics from another site here, you can use the <IMG> and </IMG> tags (use brackets [] instead of <>), and paste the url of the image between the tags.
It will display the image here, which it sounds like you are attempting to do. :smile:
FWIW, I believe a lot of HMTL code is prohibited here, so that people cannot randomly run scripts here.
