I was able to resolve the issue as was mentioned about needing to have the image of the .png divisible by 4. I use the dimensions according to the above post and now having it working. Keep up the awesome work.
I have placed the .png files in //ploader/covers.emu/ and made sure the naming structure is the same, but don't have any box covers showing up even after doing an import of snap shots. Is there a step I'm missing?
