Hi,
I’m wondering if the OP ever resolve this issue? I’m having the exact same problem. It must have something to do with my PS or my Mac. All I do is take an image, resize it, and save. Then I upload onto a webpage, the colors are totally washed out. If I do the same thing on my Winddows desktop, everything is fine.
The resized image looks fine on my Mac, and looks fine if I simply drag it into a browser. It is only when uploaded to webpage that it changes.
If I simply upload existing images that I did NOT process using PS on my mac, colors stay true after uploading to the same webpage.
So, it must be something to do with my PS on Mac. By the way, I also tried different versions of PS on the same mac. Same problem always occurs.
Can someone help?
Thanks!
