Supports image naming rules for the new iPad HD screen

After checking the apple documentation, the image naming rules are as follows:


Devices with out retina:

Imagename.png-for iPhone/iPod

Imagename ~ Ipad.png -- for iPad


Devices with retina display:

Imagename @ 2X ~ Ipad.png -- for iPad
ImageName@2x.png-
For iPhone/iPod

Applications Running in IOS 4 shoshould now include two separate files for each image resource.
One file provides a standard-resolution version of a given image, and the second provides a high-resolution version of the same image. The naming conventions for each pair of image files is as follows:

Standard: <imagename> <device_modifier>. <filename_extension>

High Resolution: <imagename> @ 2x <device_modifier>. <filename_extension>

The <imagename> and <filename_extension> portions of each name specify the usual name and extension for the file.
The <device_modifier> portion is optional and contains either the string ~ IPad or ~ IPhone. You include one of these modifiers when you want to specify different versions of an image for iPad and iPhone.
The operation sion of the @ 2x modifier for the high-resolution image is new and lets the system know that the image is the high-resolution variant of the standard image.
Important when
Creating High-Resolution versions of your images, place the new versions in the same location in your application bundle as the original.
