<p>First, thank you all for the help.</p>
<p>I have not found a solution that I'm happy with, but I think that I at least have a better grasp of what's going on.</p>
<p>First, the decrease in quality comes from the 680 pixel requirement. Exporting JPEGs from Lightroom and Photoshop using the various permutations, but forcing to 680, always results in a JPEG that I'm not happy with.</p>
<p>Peter, the diagonal cables are one of the things that was bothering me, but just one of many quality problems.</p>
<p>Lex, thanks for the tips on converting stylized images to JPEGs. I hadn't noticed some of the problems in the full sized JPEG. My usual MO is to export full sized JPEGs from Lightroom and then upload. My JPEG looks fine, but I never thought to compare it to the full sized JPEG on the PN, which is reduced to 1500 pixels wide.</p>
<p>For now, the answer seems to be that's just what a 680 pixel wide image looks like on PN. My complaint now changes to, shouldn't PN, a website where photographers critique each others photos, do at least as good a job as something like Facebook?</p>
<p>Compare the two images:</p>
<p>https://www.facebook.com/photo.php?fbid=10100395314523765&l=2c62ec3af3</p>
<p>http://www.photo.net/photo/17934450&size=md</p>
<p>Is there any plan for PN to upgrade the way it handles JPEGs. Shouldn't it at least be able to match Facebook, or dpchallenge, or most websites that deal with photography, really?</p>
<p>Also, I've realized that I've noticed the difference more since I've upgraded to a Mac with a "Retina" display. In the past, I might not have noticed the difference as much because my screen literally couldn't show as much of the difference. Has anyone who recently upgraded the quality of their monitor had the same experience?</p>
<p>And, shouldn't PN be on top of this type of thing? For example, the "photo.net" on the top left of every page is blurry on my screen, which is something that happens on websites that haven't been optimized for newer monitors.</p>
<p>So I'm a little disappointed because it seems the only thing I can do is wait for PN to get an upgrade, but at least I think that it's not really something I've been doing wrong. I've been hitting my head against a wall for a while trying to work this one out.</p>
<p>Thanks Again,</p>
<p>Tim</p>
<p>And other thing, when you type something in the reply box and press enter, the space is bigger than it will be when posted. Why PN, why?</p>
