Some New Grunge Masks

 Been playing around in PSP, making some masks ... sharing some here now.  Remember, in PSP, if you want to switch the black and white on the mask you can do one of two things:

1.  Go to Adjust  > Color Balance > Negative Image -- this will switch the white and black
2.  In your layers palette, on the layer you want to use the mask on, just right click, go to New Mask Layer  > From Image ... when the window comes up, use the drop down to choose the mask file (make sure its minimized in PSP first) and then at the bottom, select "invert mask data" and it will switch the black and white on the mask.

Here are the masks - just click on it to make it larger, then just right click/save as. 

 They should all be in jpg format.  Enjoy!!
