Won't display one specific image, others are okay.

I’ve uploaded this image to two different installations. They both exhibit the same problem. The image doesn’t show in the media gallery. It doesn’t show when a page to which it is added it rendered. But it does show on the edit page of the media gallery. It also shows on the rendered page if I click where it is supposed to be. That takes me to the attachment page, where it is visible, and when I return to the main page, it is now visible there, too.

I’ve uploaded other images both before and after I uploaded that one, and they’re fine. It’s just that one that’s causing a problem. It was created in Photoshop and saved as a jpg.
