In the finder I see these JPEGs I got from a client as having larger image area than when I open them in any app. Is there a way to "uncrop" the JPEG to show the full image in an application? Thanks.

iPhoto keeps a copy of the "original" version of a photo if you edit it. So if you cropped them in iPhoto, you can revert to the original. If you cropped them elsewhere, the information is gone, thrown away, in the digital nirvana.

What you see in the Finder is a preview icon. The Finder can create those either "on the fly", i. e. repeatedly from the image data whenever you view a folder, or it can use a "custom icon" which has been stored in the resource fork of the file. The Finder does not create such custom icons itself, but some image editing applications like Photoshop, GraphicConverter etc. as well as Internet Explorer do.

So what probably happened is that some application created a custom icon for the image which was not updated after cropping (maybe because it was cropped with an app that doesn't support custom icons).
Nasrudin sat on a river bank when someone shouted to him from the opposite side: "Hey! how do I get across?" "You are across!" Nasrudin shouted back.

Yup, looks like that was it. I stripped the metadata/EXIF data out and the new preview was the cropped image. Thanks.
