Development of the WTU Image Collection began in March 2004 with financial support provided in part by the Washington Native Plant Society. In 2007, funding from the Puget Sound Mycological Society and the Daniel E. Stuntz Memorial Foundation enabled us to begin adding lichen photographs to the Image Collection. In 2017, additional funding from the Puget Sound Mycological Society allowed us to add fungal photographs and descriptions to the web site, and modernize the web site's underlying infrastructure and web pages.
Distribution Data for the species maps is derived from the Consortium of Pacific Northwest Herbaria Database.
Nomenclature and synonyms for vascular plants are based on the Washington Flora Checklist. Additional descriptive data for vascular plants, including species descriptions, phenology, distribution, habitat, and common names are based on a variety of sources including the 5-Volume set of the Flora of the Pacific Northwest for those treatments therein that are still valid.
Nomenclature and synonymy for macrofungi is basd on a draft checklist maintained for the Consortium of Pacific Northwest Herbaria combined with a state-level checklist from the Pacific Northwest Key Council. A portion of the photographs and species descriptions for macrofungi were obtained, with permission, from the book Mushrooms of the Pacific Northwest, published by Timber Press.
The following individuals have assisted with compiling large portions of the vascular plant descriptive data: Ken Davis (bloom period data), David Giblin (identification key data), Don Gowing (bloom period data), Don Knoke (distribution and habitat text), Barbara Williams (bloom period data), and Linda Brooking (identification key).

The University of Washington Herbarium and its partners have released plant identification apps for the wildflowers of Washington (1,021 species) and Idaho (810 species), based in part on information contained in the WTU Image Collection web site. The apps run on Apple, Android, and Amazon Kindle mobile devices (both phone and tablets).

This printed field guide by Steve Trudell and Joe Ammirati covers more than 450 species of macrofungi found in Washington, Oregon, Idaho, western Montana, and British Columbia, with an emphasis on forested habitats of western Washington and Oregon. Many photographs and species descriptions from the book are reproduced on the WTU Image Collection web site, with permission from the authors.
