Chronium is a flexible JPEG viewer and database with a search engine that allows users to find pictures based on queries or find pictures resembling the current one. Content and similar searches are useful to quickly locate pictures the user wants to view, or wants more of the same kind. Chronium imports folders of JPEGs, lets the user categorize them, and saves the results in a database file. Also, unlike ordinary databases, Chronium's free-form intelligent database allows users to categorize JPEGs on the fly while viewing them, and invent new categories and keywords as needed. Chronium even plays music in the the background for added ambiance.
