Simple Monitoring tool

In short: -= Create a page that would show in one page multiple sites pages. =- Explanation: I need to check that all my site are up and running, so rather then opening tens browser to check it, I want to be able to check it all at once. The page would refresh automatically every x seconds. Look at the attachment to see what I mean. * It should be written using as base coding language, PHP. * There is 2 pages, one shows up all the pages, the other is for configuration. * In configuration we can: -> Add/remove URL -> Choose the width of the miniature -> Set the refresh rate in second. I'm not talking about screen-captures of the pages, I want to display the page in a reduced size. This is a simple project, so I'm not considering high bids. Don't hesitate to ask me question about this project, I'll be happy to answer them. Friendly, Rui
