i think...i'm not sure...lol but if you can't load it then you have to dl the image then turn it into brush here's the step to load it into your photoshop.
when first if the folder is zip, unzip it then go into your photoshop and click on the brush tool.
after that you just play around with the brush...like just stamp it anywhere on your graphic. ^^ hope that help if you need anymore question ask me ok! ^^
