When I try to open a TIFF file in Photoshop CS3 i got an error dialog saying "Unexpected end of file encountered" and I am not able to open the image. The same image can be opened in Illustrator and other image conversion tools without any error. How is it possible???
I have no idea as I have seen this maybe once or twice. and those were files from other people that had been emailed to me. If you can open and save it in some other app do it. I would also run Diskwarrior as well as routine maintenance
