You can have a link from your web site to your Album Index page for clients to view and order. This is the best way to use TimeExposure's WebGallery and setup of this feature is covered in the article "Using WebGallery".

WebGallery supports multiple index pages, so if you wish, you can have different index pages for different types of jobs and/or portfolio categories. Since your web site can directly link to each index page, it is easy to display and offer a large collection of images in a structured fashion that you can maintain and update yourself. You can also give each index its own name and optionally cross-link each index pages on other index pages.

And with the customizing ability of WebGallery, your Index pages can match your web sites graphics and colors.
