I pasted the url of the image in between the img tags, but still don't see anything. Can you explain what I'm missing?
I get the same result when I copy your URL (http://www.naturescapes.net/portfolios/pics/userpics/53266/2_3345.jpg) into a new tab in my browser, which makes me suspect that your website doesn't allow direct links.
Indeed. I think I'll give up on the one, it's becoming too much trouble. I see the images fine on my desktop monitor, but when I use another computer I get the red square too. Thanks to all anyway.
