Well you are the lucky one from unlucky people, in your case dreamweaver went crazy as you been playing around with image swaping.
There is something wrong with script logic in "MM_swapImage", and I can't figure out what.
The thing is, when you click on thumbnail, central image is cleared and nothing appear. However if you try to see if the image exist you will find it, example :
http://www.conceptwheel.com/images/c...brookwade1.jpg
then go back and click on same thumbnail and your image appear.
What I can sugest is to clear your HTML code of all scripting and save, than again build all behaviors.
To do so, delete whole SCRIPT section in head of html document and delete this parts
<A onmouseover="MM_swapImage('thumbbrookwade1','','
/images/catalogues/thumbnails/thumbbrookwade1pink.jpg',1)"
onclick="MM_swapImage('blankimage','','
/images/catalogues/brookwade1.jpg',1)"
onmouseout="MM_swapImage('thumbbrookwade1','','
/images/catalogues/thumbnails/thumbbrookwade1.jpg',1)"
href="javascript
:;"> </A>
which are attached to your thumbnails.
This only thing what I can think of, other solutions are to complex without any knowlege of scripting.
Let me know how it whent on
