Help with Album Art

[dravp]

Hi, 

 

I have multiple music folders / albums on my android tablet that I play with Poweramp player. These folders are individual collections of songs that I have (so, no actual "album"). So, is there a way I can assign a picture to that folder which can be seen from the folder view screen? I tried putting in "cover.jpg", "folder.jpg" "albumart.jpg" pics in folder, but they do not pop up on the folder. 

Any suggestions..??

Thanks
