We use an image compressor on our wordpress site to enable it to load faster, and have our JPEG compression set to 80, which is unnoticeable for our images. eBay seems to want a quality of 90, so when we submit our images it iffues between 6 and 12 warnings per item uploaded. It woul dbe good to have a box in teh settings where you could paste in teh Warnin IDs of any you didn't want to see anymore.
