how can I develop a custom cpanel visitor report or raw log analyzer?

Hi,

I want to have a password protected directory where family members can log on and view my photo gallery.

The question is I only want to see the traffic on images, not html pages. For example: latest visitors report or even the traffic reports only showing requests for the images.

I want to be able to only see traffic on jpg's and .gif's only and sort them in order of popularity.

Or is there a simple log file analyzer that can sort this out for me but be customizeable so that I can see domain, ip, referring pages, or login information?

I am familiar with php and can customize a tool if someone can referr me to one?

Thanks!
Rick
