In my opinion, both choroba and marto are right... but you're still going to have problems.
  1. on a "300px by 200px world map" your "blinking .gif dot" is going to have to be nearly (or maybe more than) big enough to obliterate Texas, and portions of adjoining jurisidictions in order to be seen. I tested, (with my somewhat elderly and inefficient Mark I eyeballs) with a 5px black dot, on a commonly available world map after reducing the map to 300x200px.
  2. Attempts at mapping IPs to geography commonly results to mapping the location of an ISP, not of the user (with possible exception of those with a dedicated IP and a backbone to a big pipe)... and if the user is confined to a dialup link to the ISP, the location could be off by most of a continent.
Not recommended!

P.S. None of the above considers the users visting thru an anonymizer
