In addition to describing what is shown, an element can have an "unseen" field, where things related to the image but not appearing in it can be mentioned without creating misleading search results.
The technical data (Exif or DCF) embedded in files from digital cameras is imported into the database at the same time and can later be used in searches.
To be compatible in this way, the external image editor must accept a filename as an argument i.e. in response to the command editor.exe,image.jpg the editing program editor.exe must open the file image.jpg.
There is also a full metadata editor for creating detailed descriptions and an advanced search function to seek images that meet a complex set of rules.
Image classes appear to be directories (folders) but their names and relative positions are determined by information in ViewMinder’s database, not by their location in the Windows file structure.
