When you say "identify", I assume you mean ImageMagick's identify. If the
"-verbose" option doesn't give you a specific resolution for an image, then it
doesn't have one. Most software will then default to 72DPI.
You can set the resolution with the "mogrify" utility, like so:
mogrify -density 300x300 -units PixelsPerInch foo.png
Hope this helps.
