Modify PHP+Javascript image upload script

Shinichi Tomita has solved a problem causing images uploaded in HTML5 apps on IOS6 safari to be squashed and turned around (wrong orientation). I need his scripts modified, so that: 1) The image gets uploaded to the ./uploads/ folder in three versions using PHP: a) one in the original size and quality (name post fixed with string "_ori") b) one in a maxwidth=300 and maxheight=300 version in 0.5 quality (name post fixed with string "_300") c) one in a maxwidth=600 and maxheight=600 version in 0.5 quality (name post fixed with string "_600") 2) These versions gets previewed beneath the 3 images that are previewed by default by the existing script The script code can be found here: [login to view URL] Preview script here: [login to view URL]
