Gravatar screwing up image colours / gamma

    I am trying to upload an image to Gravatar for our bug-tracking system and am having issues with the colours. Specifically, Gravatar appears to be messing with the brightness or gamma somehow.

    Here are some screen-shots of what’s happening for me:

    Things i have tried:

    – Re-saving the image with different editors
    – Re-exporting the image with different colour profiles (sRGB, generic RGB, Adobe RGB)
    – Stripping gamma and profile information with ImageOptim
    – Various combinations of different profiles and stripping/not stripping gamma

    I have also tried saving as GIF instead of PNG — the same problem happens.

    If i use JPEG, i do get accurate colours — however, Gravatar’s re-compression pretty much destroys the image quality.

    Is this a known problem? I can’t find anything online or in the FAQ.



    What is the URL of your blog please starting with http://



    I don’t have a blog. I have an internal bug-tracking system which supports Gravatar, and am trying to set the avatar for our VCS account.

    In any case, the problem is not related to the third-party sites that the images are being displayed on — it is on the Gravatar site itself.
