Expression Graphics® website templates are coded and sliced in HTML with their source files in PSD format (Adobe Photoshop) unless otherwise indicated. Please read the Frequently Asked Questions for additional information. Most of our website templates require intermediate to advanced knowledge of Microsoft Expression Web, and Adobe Photoshop. Other templates such as storefronts like osCommerce templates require a good foundation in applicable software. Please see the required software section on each template preview for these requirements. Buying a website template is not a substitute for experience using these programs.
