I would think that a heavy Image compression has to be applied to all uploaded files. Can you imagine the storage capacity required for everyone's images? HUGE!!!
Yes I can. This is one of the reasons why I pick what I feel is very good subject matters to post. I try not to post things average, mundane and the like. However, if something is of educational in value, descriptive of a process/technique/method/what not, things higher end, good quality and the like then I see that as a very good step forward and something worthy of the increase.
So, Ed, is the server still altering the photos? Wasn't that the issue?
Honestly I do still see some things changing still but not as bad as before. I have been testing various images to see what it is and so far it appears not to be the upload but the displaying in the threads. If you open the attachment by itself the size is different and with out the colorshift. It might be on my account/browser and am going to try it with various monitors and see what they show.
The changes made has been a big improvement and for that I do appreciate it and thank you.
If you do a checksum on the file you upload and the file the server delivers, are they the same? As far as I can tell, the way I have it set for your tests, the server is not processing the image at all. It's uploaded and stored as-is. It should be identical. byte for byte.
The files seem to be the same which means that it is possibly something like CSS. Also worthy of note is display on HH's is less drastic of a change in the previously posted versions, as from desktops.
Would it be worthwhile to do the resize to the 960x but leave image quality unchanged at 100?
