Anchor Square Thumb Image

Is it possible to adjust the thumbnails that are being generated to anchor at the top instead of in the middle of the image? Many of my images of people have lost their heads in the cropping process. I know if I change the canvas size using Photoshop I can select where to anchor the crop. Any possibility of doing this for the thumbs? I know I could use the straight thumbnail image, but I prefer the uniform size of the square thumbs.

You can change the gravity (anchor) of the thumbnails by editing the configi.ini file in your Omeka install. You might want to also install the Derivative Images plugin if you do this, in order to refresh the existing thumbnails on your site.

Thanks, Megan - worked perfectly!
