Check if External Image Exists

[benn_jgh]

I'm trying to check if an external image exists. Although there are already several ways to do this in PHP (getimagesize(), fopen() etc), none of these ways are near fast enough. I posted this in the hacking section because I need a very clever way to quickly check whether or not an image exists and I know there isn't a standard function for this.

Thanks

So are you asking how you extend php to do this? I dont think your going to get much quicker than getimagesize(), but you might start by looking at the code for that.

You do know C right?

I'd believe file_exists() is faster.

I'm sure file_exists() doesn't work for external images though?
