Browser don't work like images softwares. I doubt this is due do laytheme but more of a general issue with web.
Open the image on your computer from the browser (drag&drop the file to your url bar should do the trick). If the issue appears, it's definitly a browser issue.
(If not, you can still give it a try, but i'm not sure this will solve that !)
My fix :
First step (this is probably the issue) check the image color profile. Prefer basic sRVB, Web coated RVB (i think).
Check color depth (should be 32bits/8 bits per layer). Thought exporting to jpg or png should set will this anyway.
If you have lots of images you can do a photoshop script to export all.
Once your files are ready, you can fine tune the colors if any modification happend during the process. But now : what you see should be what you get on (though it might never be exactly the same).
Hope this helps !
