Validation Question

[Papajo]

I need a script that would only allow url's with gif or jpg extentions
to be entered into a text input form, anything else would get a alert
pop up.
Any help is appreciated, Joe

var ext = /\.(?:jpg|gif)$/i;

alert(ext.test('x.jpg'));
alert(ext.test('x.gz'));

Don't ask me how to validate the complete url haha, there are quite a
lot of ways to write an url and I won't make a regexp for you, so,
google it a little :]
