Hi Paul,
it is nice and easy to develop page in dreamweaver, but you always get in trouble if you do not understand basic principle of HTML, CSS and little of scripting.
Don't worry I not gone bully you over that, will try to help you if possible. Last year I had had similar problem when my teacher rush me with my final work on project and I was forced to use Dreamweaver (still prefer typing me code).
For this purpose I used catalogues.htm from your site. Go to deamweaver and
Design view, click on first thumbnail which id is "thumbvgcatalogue2", then go to
Code view and you see this.
[html]<A onmouseover="MM_swapImage('thumbmwcatalogue1','','/images/catalogues/thumbnails/thumbmwcatalogue1pink.jpg',1)"
onclick="MM_swapImage('blankimage','','/images/catalogues/mwcatalogue1.jpg',1)"
onmouseout="MM_swapImage('thumbmwcatalogue1','','/images/catalogues/thumbnails/thumbmwcatalogue1.jpg',1)"
href="javascript
:;">
<IMG id=thumbmwcatalogue1 height=95 src=""
width=100 border=0 name=thumbmwcatalogue1></A>[/html]
Have close look at image tag "IMG". Is there anything wrong? Something missing?
You are missing source image for first loading.
src="/images/catalogues/thumbnails/thumbvgcatalogue2.jpg"
That should do it for you now. Any more troubles let me know
