Description Author  

This class can emulate getimagesize function remotely using cURL.

It can retrieve an image file from a remote server using the cURL extension to send HTTP requests to that server.

The class implements a function that works like the original PHP getimagesize, except that it works for getting the image size and image type metadata of images retrieved from remote servers where fopen wrappers are disabled in the PHP configuration.

Besides the original getimagesize function metadata, it also returns the image file size.

The getimagesize function is very useful to get the dimensions of images read from local or remote files.

However, if the fopen wrappers are disabled in the current PHP configuration, getimagesize cannot get the dimensions of remote images.

This class implements an alternative solution that relies only on the cURL extension.

Image cURL: Image class to simulate the getimagesize() function using the cURL library

Image cURL is a class that utilizes the cURL and GD libraries to simulate the getimagesize function where webhost have disabled the fopen wrappers. Image cURL is a "drop in" replacement that returns an array with the exact elements. Additionally, the image filesize is returned. This class is useful when requiring information from remote linked images to check filesizes and image dimensions for publishing restrictions.


Image cURL Features:

    * Drop in replacement for the getimagesize function where the fopen wrappers are disabled.
    * Useful for getting image dimensional information when using the GD library.

Image cURL Restrictions:

    * Number of colors is returned instead of bits. cURL cannot supply this info.
    * Colors returns an unsigned integer for 8 bit palette-based images.
    * Colors returns 0 for 16+ bit true color images.	
Image cURL Requirements:

    * PHP 5.4+
    * Enabled GD extension
    * Enabled cURL extension
