ZScreen automatically uploads a JPG instead of a PNG if the file size is 
greater than
350 KiB. 

Are you comparing an uploaded JPG to ImageShack/TinyPic/FTP to an image pasted 
from
Clipboard to Adobe PhotoShip? 

If you are then, JPG is a lossy format and you will see artifacts compared to 
the
original Image pasted from Clipboard. The original files in PNG (Lossless) are 
saved
in the Images folder.

I guess the compression isn't great? These are being uploaded by FTP directly 
to my
server, not sure how I can improve quality and still use a jpg. See
http://wotlkwiki.info/chaud/example.jpg or the attached.

Thanks for the example. 

When you compare the Image from Clipboard in Adobe Photoshop with the JPG 
created
using ZScreen, you are comparing a lossless BMP file to a lossy JPG file. In 
order to
accurately compare you will need another JPG file. 

JPG compression isn't great. We are using standard .NET methods to save them as 
JPG
files so we are limited to what the .NET Framework has to offer. 

My suggestion would be to use PNG instead of JPG. If you find ZScreen is 
switching
from PNG to JPG very often, then increase the "Switch After" file size from 350 
KiB
to something higher like 512 KiB or even more. :)

ZScreen will by default set this value to 512 KiB to avoid JPG creation at 
lower file
sizes
