You really can't reduce the size the images takes up in memory.

When an image is loaded, basically a UIImage object the size wil be width x height x 4 bytes. That is the size the an uncompressed image will take up in memory. Since you can use compressed images all image, once loaded in a UIImage will be uncompressed.

If you really need so save some memory, save the image to disk and create a thumbnail which you use in your app. Then when need you can load the larger image and use it,

Try using the Resize method in UIImage+Resize.h

 [aImgView setImage:[ImageObjectFromPicker resizedImageWithContentMode:UIViewContentModeScaleAspectFit bounds:YourSize interpolationQuality:kCGInterpolationHigh]];
