There are 2 images in the file. These files can be used as tiles 8x8 or 16x16.
What software are you using? if your software doesn't have the function to use an image like this as 'tiles'then i will be happy to generate a 8x8 tile/ 16x16 tile set for you. (bu these are a lot harder to use that way).
Does your download files contain these images? sorry for the inconvenience. :(
