gerkintrigg Posted December 13, 2010 Share Posted December 13, 2010 I just include a pretty generic image resize script which I then call. If you would like this script, then let me know (on this board) and I'll email you it. Or if you follow me on Twitter (@manteya) then I will message you my email address.
