Dear scientists,

Owing to a series of recent incidents where my photographs have been used in technical papers without my consent, without credit, and released under Creative Commons licenses, I am sorry to announce I am ending my policy of free use of photographs for scientific papers.

Future use of my work will require a paid licensing agreement, the same as for most professional uses of copyrighted content. There are two exceptions. First, if I have photographed captive animals in your laboratory, those laboratories are allowed use of the associated images without additional permission, as long as those uses don’t involve releasing the images under a Creative Commons license. Second, use of the photographs as primary data should be considered fair use and is allowable.

Use of my images in presentations and classroom lectures is still allowable if credit is given, but please be aware that uploads of presentation slides to the internet requires a photo credit be given next to the image to prevent the appearance of being orphaned.

I regret having to tighten my policy, but my photo business has been my primary source of income for the past few years, and I cannot continue to afford producing and hosting natural history images for the myrmecological community to use if my guidelines are routinely sidestepped.

Thanks for understanding,
