Allow public:// for entering image paths

Because the module wasn't working correctly (no offense and maybe all errors I got were already fixed) I created my own methods within my template.php file and I'm using exactly what you are requesting.

@dev It's very easy to get the real path to the image. As far as I know, it's possible to pass any URI to these functions, the check for public:// themselves.

// Without image style.
$vars['og_image'] = file_create_url($image_path);

// With image style (crop + resize to 130 x 130).
$vars['og_image'] = image_style_url('og_image', $image_path);

It would be best if the module directly provides the og_image style (crops + resize to 130 x 130; which is the preferred format by Facebook). Hope I was from any help.

Lets make this generic.

This seems like it should work - any image URL values that start with 'public://' are passed through file_create_url().

This one actually works ;)

Going to sneak this into the next release.

Committed.
