Reply #76: Ah, but you cannot "simply copy" the photo and re-post it. [View All]

You must save it as something. Anything. And that is almost always a .jpg for web publication. So, how can you copy and repost without going through the re-save process? It sounds fascinating, and potentially time-saving.

And this wasn't "simply copied" anyway. It was enlarged, THEN saved again. Those original .jpg artifacts got enlarged when the picture was blown up, then more artifacts were added to the artifacts when the photo was re-saved. There simply is no way aroung this. None, except for posting in .png format, which no one does because most flavors of IE don't support it.

I am not trying to argue. I respectfully submit that you're just misinformed. You cannot copy, manipulate, enlarge and re-save to .jpg without adding artifacts, unless you used a "10" (or, "12" in PS) setting. 12 in PS is virtually lossless. Note, I say virtually, not totally. You seem to assume that I am saying everyone saves pictures at the "2" setting. I am not. "6" is considered "high quality," and it is loaded with artifacts when enlarged. Reuters posted that pic in a slide show on Yahoo, too. That is where I first saw it. And you can bet your bandwidth that that photo was saved with no more than a "4" or "5" medium setting. Because it is only the web, and the artifacts tend to get lost on displays. Plus, as a slide show, the picture must load quickly. At the size of that photo, I'd be totally stunned if they had compressed it any at anything but a "4" or "5." There simply would be no need.
