You could basically regenerate static pages (e.g. with a background server process) each time a report is received. In fact, you'd only have to regenerate the ones that have changed, not all of them will change for a given new crime report.

These are static pages that get recreated every 15 minutes, even thought the meta-refresh tags update the pages every 10.

It's a performance issue with firefox. I've done some preliminary research on the issue and google knows about it, but I haven't found any fixes other than preloading the images, which I am trying.

I called myself fixing that. I'll run fireworks on the images and have it optimize also.

>- I'd consider a sans-serif font instead Times (New) Roman. You might want to rationalize any style sheet(s) you may be using

Good point.

Thanks for the criticism?<g>
