Getting Image size With no Upload?

[Monkuar]

Is there a way I can get the .jpg file in kilobytes from a remote url and check it to make sure it does not exceed 40 kilobytes before it saves the remote url into my database?

maybe in internet explorer (with VBScript) but for the most part.. JavaScript is very limited in what it can do with the hosting computer..

Here's kind of a hack way to do it.  There might be a better way:

$content = file_get_contents("http://www.example.com/path/to/image.jpg"); 

$handle = fopen("image.jpg", "w+"); 
fwrite($handle, $content); 
fclose($handle); 

$size = filesize('image.jpg');

 

In short, you are probably going to have to download the file, at least temporarily, to get the file size.  You can always delete it right after.

You can try doing a HEAD request with get_headers() and then find the Content-Length: header.  If that fails you can fall back to a file_get_contents/strlen() combo to get the size.
