regex javascript supply valid url image

Question

I need a regex for valid url image, example: http://domain.something.jpg

protocol: http,https,ftp estension: jpg,png,gif,bmp

Can you help me please?

What about `http://foo.com/dynamic`? Do you consider this as *valid image* assuming that this server side script sets the `Content-Type: 'image/jpg'` and writes a valid image into the response? — Darin Dimitrov, Jan 21 '12 at 09:38

Maybe something like that:

"^(https?|ftp)://.*(jpeg|png|gif|bmp)"

that doesn't cover the ftp protocol – Marcelo Diniz Jan 21 '12 at 09:56
Just realized that, altered the regex. Thanks for the hint. – Ortwin Angermeier Jan 21 '12 at 09:58

Try this,

/^((https?|ftp):)?\/\/.*(jpeg|jpg|png|gif|bmp)$/

I'd suggest to add "bmp" as another valid extension. – david Sep 24 '14 at 12:41
