Are you looking for something for your website? Do you want to create thumbnails on the fly? Do you have a php enabled server?
I'm confused about the email to weblinks part of the question, could you elaborate a little more?
Thanks Bryan, what I mean is that, where photoshop automates a email link on the page of thumbnails, I change that in dreamweaver to a link to a pdf order form so that people can download it. Problem is that for page designs that have several pages due to a large no of thumbnails, I have to go and change it for every page. And it is not possible to do it for some as the large image has its own page and it is not practical to change it in dreamweaver on every page if there is a hundred images. Does that make sense. Also, in PS, when you change the thumbnail above 100 pixels to say 120, it looks like 100 pixels resized up rather than the image being resized down to 120. if you choose 150 px the thumbnail just looks terrible so it is pointless. What would be good would be if the large thumbnails had as much clarity as what they have when they get viewed in Bridge when they are small. Thanks for your help, Gary.
