restricting dimensions of linked images

[The Keeper]

Hi I want to restrict how big someone can link an avatar (I'm using a hack that lets you link off another website rather than upload)
however it places no restrictions on file size, is there any way to set up a thing that checks a file's size/dimension when it is put in a form?

Hi,

the the PHP function getimagesize() you can get the dimentions of an image.

Try this:

PHP Code:

print_r(getimagesize("http://www.php.net/gifs/php_logo.gif"));
