I agree. Using images to track site hits is a typical mobile sites trick, but this is a very interesting application. I wonder if you'll be able to collect a list of IP's of companies; so you can tell if someone from Yahoo! or Google or XYZ has accessed your resume.

yeah that'd be great, it'd have to earn enough to pay for the full GeoIP database though, it's running on the free one now

IP address geolocation SQL database: http://ipinfodb.com/ip_database.php

>The SQL database behind ipinfodb.com is offered for free. We offer the database in different formats (SQL, CSV), city or country precision, 3 or 4 IP digits precision and data in single or multiple tables. Available information in the database : ISO country code, country name, FIPS region code, region name, city, zipcode, latitude, longitude and GMT/DST timezone. The database is updated during the first week of each month.

thanks, I'll check that out!

Wait a minute, are you saying there's a database you can buy that tells you the IP addresses used by every company in the world? That's awesome.
