Hello I am wanting a way to show PDF as thumbnails then to click and expand,,,there going to be for sale, but what iam showin on the site is not what they recieve via email as its a larger file,,

any ideas of a module that will show a pdf, let me add links and a catalog format?

There are several options depending on what you're comfortable using.

You can try Phoca Downloads.extensions.joomla.org/extensions/extensi...load-extensions/7993

or Docman extensions.joomla.org/extensions/directo...tion/downloads/10958

Shopping carts like Virtuemart and Hikashop also accomodate downloadable products. You may be able to accomplish exactly what you want with shopping software.

In any case you'll probably need to create an actual image to use as the thumbnail.

Let me know if that helps narrow it down for you. There are many ways to do what you want. Searching the JED will give you a lot of choices, but we'll help you narrow it down if we can.

Cheers,
Ed
