For those who don't know what DHTML stands for, it is:  Dynamic Hyper Text Markup Language (or Dynamic HTML).  Basically what it does, is allows various fun things to happen to a website.  Such as, if you are using Internet Explorer, you'll notice that as you scroll down the webpage that the background stays in a fixed position, where as the content of the site continues to move.  That is an example of DHTML (there are so many different tricks out there for DHTML).

     The one thing [noticed so far] with the guestbook, is that none of the images from my server seem to appear in the IE (Internet Explorer) browser - such as the horizontal bars (the bars that seperate one section from another...example:  the greenish image bar below is a "horizontal bar image"), or any other images for that matter.
