Hi there

its about this thread, or more specifically the pictures posted in it:
http://ball-pythons.net/forums/showt...s-the-big-deal

the story: someone posted some pictures of orange dream combos, and i looked up orange dream combos at worldofballpythons.net . i found one if the pictures he posted, but the two versions of the same .jpg have different colors. So i posted the two pictures side by side, and others could not see the difference. but i could see a clear difference.

these are the two images in question:

do these pictures look the same to you or can you see a difference? I can certainly see it.

according to the poster of the second image, it has been produced by first sharing the picture from WOBP on facebook, and then linking directly to the shared facebook image. what REALLY confused me is that apparently some people see the difference and others dont.

so i made a screenshot about how the thread with the two pictures looked like to me:



and now everyone could see the difference.



its a real mystery to me, could it be that facebook did something to the color balance of the image? also i know nothing about .jpg image metadata and stuff like that, can someone tell from the image when and how it has last been edited maybe? or has the file been corrupted as it got copied from server to server?

i noticed that the filesize went down from 97KB to 35.6KB. But how can compressing it mess up the color so much? Maybe a bug on facebook/instagram? And on my end, i use a fresh installation of windows 7 with updated firefox, and made and saved the screenshot with programs included in Windows 7.

i think its some kind of weird technical glitch and dont think that someone intentionally did this, but thats based on what i think about people and not based on any knowledge of the technology involved. i think it may be a bug worth reporting, the bug could be in facebook, or in instagram-technology used by facebook, or in windows 7, or in firefox.

Any ideas? The bug caused a lot of confusion in the other thread, and with the softwares involved it could be a bug affecting millions of systems and/or millions of pictures shared on facebook. But i lack the knowledge to figure it out.
