Problem using url filename with space not encoded

[andy2mar]

If we have an url image name with space not encoded, for es.
$FastImageSize->getImageSize('https://example.com/some random image.jpg');
the function will not work because the file_get_contents do not accept url not encoded.
As a fix, I propose to automatically encode the filename in the getImage function.
$filename = urldecode($filename);
$filename = dirname($filename) . '/'. rawurlencode(basename($filename));
$this->data = @file_get_contents($filename, null, null, $offset, $length);

I can confirm that this is an issue.

We've noticed it via the AMP module for Drupal, which uses the Lullabot AMP library which, in turn, calls this library to determine the width and height of images if they're not already present as image attributes. This fails for images that have spaces in their filenames. There is a Drupal.org ticket for this issue.

I'm fairly certain the same issue should apply when using the PHP native phpgetimagesize library as that should also not automatically urlencode paths. Therefore I think this is an implementation issue on the library or app calling the library.
