Image Dimensions not showing

This MAY be a Photoshop CS3 issue, so forgive me if it is, but I can no longer see image dimensions in the (Leopard) finder. The problem seems to have started when I upgraded to Photoshop CS3, but I upgraded to Leopard just a few days prior to the CS3 upgrade. If I look at images that were already on my hard drive before Leopard, the dimensions appear. Any new images I save via Photoshop no longer have dimensions appearing in the finder preview area.

Edit: This definitely appears to be a Leopard issue. It appears that ALL new images, no matter which program saved it, do not have dimensions attached. I opened a jpeg with Preview and saved it as both a jpeg and a png, and no dimensions appeared.
