Sentinel Visualizer lets you display specific images for entities and entity types. When Sentinel Visualizer creates a new database, it includes some basic entity types with pictures. You can add entity types and entities with your own graphics or choose among the thousands we include with the product.
While Sentinel Visualizer includes some basic weapon graphics, it doesn't compare with the wide range of pictures offered by the ATF for shotguns, rifles, revolvers, pistols, guns and ammunition, which they are constantly updating.
The ATF weapon pictures are part of their public Resource Center and property of the ATF. We can't distribute them. but you can view, download and use them subject to ATF terms.
Find the photos you want, right click and save them to your PC before loading them into Sentinel Visualizer.
