Statcounter should do the job for you, and you're not required to download the logs (but has the option if needed). Here's the thread:

There's also Google Analytics, and Extreme Tracker. Note that Extreme only tracks your "root" page, unless you purchase an account. Thread here:

Statcounter tracks all galleries, and images giving you the visitor path, IP, page of entry/exit, keywords and links someone followed to your site. Google Analytics is set up somewhat differently, but full of information too. Both are very effective, only requiring code added to your profile and free.
Enjoy!
