How can you import a JPG as an apperance in Visualize?

Greetings,

I have been looking over the Poliigon website and found some cool appearances I want to use, I dropped the new .jpg's I downloaded from Poliigon.com into the Visualize Content / appearances folder and then try to grab it in Visualize and I does not recognize the file format.

Is there an import wizard that will convert the .jpg to a format the software likes. Can I not use any jpg file formats for appearances?

Any help here would be greatly appreciated.

Regards,
