</div>Which makes me believe that the program (you're not saying what you're<br>
using) thinks the images have 300dpi.<br>

What's the output of<br>

- "jhead -v" (from jhead)<br>
of the picture? Can you put one online for study?<br></blockquote><div><br></div><div>I just installed imagemagick. The output from "identify -verbose" is below.
