Basic usage

• url - the url of remote image to be converted (and cached)
• w - width of resized image
• h - height of resized image
• q - quality of resized image (default is 92)

the url parameter must be encoded, otherwise unexpected behaviour may occur.

• the url http://www.google.com/images/icons/product/apps-128.png
• becomes http%3A%2F%2Fwww.google.com%2Fimages%2Ficons%2Fproduct%2Fapps-128.png
