How do I see where pin images are located?

Dropping pins with Images geolocate those images. You can see exactly where all images are on a map

In your project dashboard, all images attached to pins will be shown is the images area. It will look like this:

When you right-click on an image a few options will pop up

Clicking zoom to pin will open up a new tab, zoomed into the pin associated with that image and all other pin information.
