I have photos on my computer (from assorted crappy digital cameras of friends) and occasionally I'll notice some are corrupted, with about half of the image (bottom half in every case) grayed out in a complete gray solid color. However, when looking at these images in finder, the built in preview shows the image COMPLETE, with the gray areas not apparent. Problem is, this is just a thumbnail, and an extremely low resolution. Double clicking the file opens the image at fullr esolution, complete again with half gray corruption. Any idea on how to bring back the image at full resolution? I suppose this means the image information is there SOMEWHERE, right?
