Marketplace purchase - looking for source map images

I bought D&D 5e Ghost of Saltmarsh from the Marketplace and created a new game.   While looking around I noticed that the map assets, not the ones in the map pull-down, but the actual map images are nowhere to be found. I've looked in the images tab and do not see any custom folder or files.  Why I'm looking for the map images is so I can create my own maps based on those images from scratch but I do not have a 'source' image to start off with.  Now, this is the first time I've purchased something from the market place so maybe this is a normal 'feature' that the actual maps are not included and if I want the map to work with I just need to make a duplicate.   Any assistance would be greatly appreciated.

This is a normal "feature".  Prebuilt maps like that are part of the module and intended to be used with it.   If you were to want to download an image for personal use, you could go to the map layer, select it, hit Z, then right click it and "save as..." to get a local file you could modify.

Thank you!  That is what I was looking to accomplish.  I appreciate the information.
