Pictures-Strange Problem-Now you see it-Now you don't?

I have a real strange problem, I set up a family and friends site guestbook and enabled picture posting. However I cannot see the pictures but others can? So I poked around checking other guestbooks made with the same program. The guestbook on this main site for instance I can see the pictures no problem. Some others I visited I cannot see but from the text I know there are supposed to be pictures there. Other sites I can see the pictures just fine. Anyone got any ideas?

This is the code I see when I view the guestbook:

<a href="public/img-1063021572.gif" target="_blank>

This the code that others see in the same location:

<a href="public/img-1063021572.gif" target="_blank"><img src="public/img-1063021572.gif" align="left" border="0" width="250" height="65"></a>

The difference being the img src file code of course doesn't show up on my computer?
