My server had php5 and php4 both installed, and defaulted to php4, unbeknownst to me. At any rate, it had some slight difficulty running with php4, but the author spent tons of time helping figure out what exactly was wrong. He managed to fix it, and then I discovered the fact that php4 was default. That's fixed now and version 0.5 works flawlessly.
It's a nice alternative to flickurpic, especially since it's free. It's also pretty simple to use. I'm looking forward to future releases of this program and any others that might be coming down the pipe!
