I maintain/manage some Websites that are developed by outsiders. Some of them are stuck (for one reason or another) using older tools and software packages … namely Microsoft FrontPage. In one of the websites, in particular, the previous method of showing a larger/zoomed-in version of an image was to open a new tab or browser window using the image’s URL.
After some discussions with the site’s creator and it’s owner, we decided to bring the design up to current practices, and use a modal dialog to display the images. So, I turned to the handy-dandy search engines and, after some searching, settled on ThickBox as the JQuery plugin to use.
