While Fotolia does not specialize in any specific subject, they are seeking high quality marketable stock photography. Stock photography covers so many subjects, cultures, issues, concepts, and ideas. In addition stock photography is always changing. What was hot last year may not be hot this year. Stock photography is essentially a catalog of photos that a potential buyer may search to find just the right image for their marketing brochure, multimedia presentation, website, billboard or other project. These buyers are often graphic designers, graphic artists, marketing professionals, ad agencies, and in some cases private consumers.
