These are great images for populating your gaming maps with one fatal flaw. The 300 dpi images are in a Adobe proprietary TIFF format and can't be used in most applications. They are also not compressed TIFF. The creator tried to do a good thing by using TIFF with layers so that users would have the option of turning off shadows. Unfortunately that means loading them into Photoshop to convert them to transparent PNGs for use in most mapping/VTT applications. The TIFF files should be replaced by PNG files either with/without the shadows.

The 72 dpi versions are just a bit too low resolution but otherwise very good. This will be a 5 star product once this issue is addressed.

Updated 2/15/2019: Updated files in PNG format at 280 pixels/grid in shadowed and unshadowed versions are just the ticket. 5 stars.
