From 2fa99602c6f6431e99468ca13f4a58344a401c24 Mon Sep 17 00:00:00 2001 From: Marc Alexander Date: Sun, 8 Feb 2015 20:46:14 +0100 Subject: [ticket/8672] Add class for retrieving imagesize without download getimagesize() always downloads the complete file before checking the actual image dimensions. This class will be able to do the same without having to download possibly large files.
