I'm having trouble with jpeg artifacts in this image I've uploaded to PN. I scanned this at 600dpi using an Epson Perfection 2450 Photo scanner. I used "Save for Web" in PhotoShop 6 to resize the image to 600x600 and save in jpeg format. I've tried many different levels of compression and I've even tried scanning at 300 and 800 dpi, but I can't seem to get rid of the artifacts. Interestingly enough, I have successfully uploaded this image (although it has a border and is slightly smaller) to my website. What can I do to clean up the artifacts in this image? Should I be using a 3rd party jpeg compression tool like Jpeg Explorer instead of PS? I'm trying to keep the size under 100k as specified by the PN guidelines. Is this absolutely neccessary? I'm sure PN will compress my image if I don't, but if that's the only way I can get a clean image...how can I tell? I've searched the archives, and there's so much on jpeg compression, etc., but I can't seem to locate an answer. Please help!
