By default, Tabletop Playground is set up to primarily use asset files, which are stored with your package on your hard drive. All users have their own copy of each asset – either downloaded from Mod.io for packages released publicly, or transferred to them by the host using Peer-to-Peer Package Sharing.

However, for Image files there is another option. Instead of using a local file, you can point to an image stored online via URL. In most cases, when you see a button to upload an image, you should see a small globe icon next to it.

Clicking this will change the “Select File” button into a text field where you can input your URL. Clicking the file icon to the left of the field will switch back to the other method.

Note that web images cannot be used for Image Shape Models, or other cases where the image would define the mesh of a 3D object.

Web images have a few advantages. First, they reduce the size of the package, and hence how fast it will be for other players to download it.

Second, web images allow players to easily change what image is used for a deck or tile stack in the middle of a multiplayer game, via an object-level override. To do this, right-click the deck in question, choose Customize → Properties, and enter your URL in the “Image URL” field. This will override whatever URL is present at a template level. (Note that this method is only available for cards and tiles, and only if “Allow Web Images” is checked in the template’s Advanced Options.)

There are of course downsides to web images as well – most notably the risk of links breaking, and the fact that they won’t display if you’re offline. You also won’t be able to take advantage of TTP’s ability to create card sheets or dice sheets from individual images if you’re using web images.
