You can use the identify command that's part of ImageMagick to do this:
$ identify rose.jpg
rose.jpg JPEG 640x480 sRGB 87kb 0.050u 0:01
The 640x480 is the dimensions of the image, rose.jpg.

$ find somedir -iname '*.jpg' -exec identify {} \;

$ find somedir -iname '*.jpg' ...

-P is needed to use \x00
To list offsets use:
grep -Pboa '\x00{NNN}' File
So something in the direction of:
for f in *; do
[ -e "$f" ] || break
if grep ...

The following should work, updated to strip white space:
#!/usr/bin/awk -f
# NR is the current line number (doesn't reset between files)
# FNR is the line number within the current file
# So NR == FNR takes only the first file
NR == FNR {
# Mark the current line as existing, via an associative array.
found[$0]=1
# Skip to the next line, so we ...
