UIImage reduce byte size

I am using following code to resize an image - it all works well and as expected...

Resize UIImage the right way

I use interpolation quality as kCGInterpolationLow and UIImageJPEGRepresentation(image,0.0) to get the NSData of that i开发者_开发百科mage.

The problem is that the image size is still a bit high in size at around 100kb. My question is can I reduce it further?

The images originate from the iPhone Photo Album and are selected via a imagePickerController.

Many thanks,
