What is the image? As in what size is it in data file terms?
That is the real question, the smaller the image in data size, the faster it loads.
If you can post an attachment of the image you want to use then I can look at it and advise you of how to get the most out of it.
Please remember to wrap any code you have in forum tags:-
[CODE]...[/CODE] [HTML]...[/HTML] [PHP]...[/PHP]
If you can't think outside the box, you will be trapped forever with no escape...
