Sincere apologies for missing the attribution. We support cc licensing and have release hundreds of our own images for public use, and would be just as annoyed as you are to find our images used incorrectly.

We have taken down the image (and those that followed in the post) and will re-post them as soon as we can verify and provide proper attribution, as per the cc license.

Thanks for bringing the oversight to our attention.

You have made proper attribution for the first monkey picture, but for my picture you haven't mentioned my name, nor linked to the picture.
I am making my pictures available under the creative commons license because I think it is the right thing to do, and I don't expect that people do not honor the obligations under the CC license, which is only proper attribution.

I do expect this to be fixed in the next week.
