Gillis Photos operates on an incredible software called KTOOLS PHOTOSTORE. I’ve been a professional computer programmer for nearly 20 years. When GillisPhotos.com was launched in early 2005, everything was created with a mix of Perl scripts to generate pieces of HTML code. Not rocket science, but adding galleries, new pages and photos was tedious and time consuming. Photostore proved to be a Godsend. With KTOOLS PHOTOSTORE, customization is easy, updates and changes are a breeze, and adding photos and galleries is simple. In addition, KTOOLS PHOTOSTORE has hundreds of features designed specifically for photo sellers. KTOOLS PHOTOSTORE allows me to concentrate on photography rather than coding and scripting. I HIGHLY RECOMMEND IT!
