You're more than welcome TCD!
Well, I believe that whatever settings you may use, the outcome won't be as crystal clear as PNG format. I believe that if we want to maintain an acceptable and more accurate outcome we should stick to PNG. I understand the limitations that Miscshots section has, so we should consider to add it somewhere else where PNG files can be supported.
If this is possible of course and if there is any adequate and available space.
Unless there's a way to use JPEG format without any compression and distortion.. if someone else knows a way please feel free to show us the way!
I used Photoshop, Coreldraw and other image processing programs and the outcome still remains "blurred".
