Are you saying that the template itself might be corrupt?
If you right click on your image (My 16 pt.jpg) and select Properties, you can go to the details Tab. With that image, You can see the horizontal and vertical resolution of 144dpi. This is your template file. I believe Photoshop was showing me "1" because 144 was too big to fit perhaps.
The "Jojo's Practice 16pt.jpg", following the same steps, reports 96dpi.
The question, of course, is why... and I haven't the faintest idea. I was thinking perhaps you have a higher-than-normal DPI setting, and opening the image on another system with a lower DPI changed it somehow, but I'm unable to reproduce it.
Are you both using the same Version of Windows? Perhaps your DPI settings differ in some fashion?
