    For some reason I feel as if I have seen a thread on this before, but I cant seem to find it anywhere. (even with search and google) Is there anyway to convert an image so it looks better on the iphone's retina display? I have photoshop if anyone feels like they want to explain or if its possible and you'd like to just do it for me :) then feel free!

    You can't just make an image bigger without it lowering it's quality, (unless it's a vector image, but this image is not and that's a whole different thing)

    And looking at that image it doesn't even look that good of a quality to begin with, the only way is if you have a bigger image or remake it, larger.

    ENHANCE!!!

    I feel bad for this generation of kids that grew up watching too much CSI

    also I'm 80-90% sure you didnt pay for that copy of Photoshop, just from reading your post

    Images that are exactly 960x480 will look the best on the iPhone 4 display

    nah not csi... i knew it was too good to be true but maybe it was just deja vu or something. and you should raise your estimation to about 100%...

    Photoshop gives you a couple options for resizing an image. If the image is iPhone 3G size you can increase the image size by 200%. Photoshop gives you a couple options for resampling of the image. Bicubic, bilinear and etc. This will remake the image at a higher resolution and interpolate the missing pixels.

    here is a resampling of the image at 200% using nearest neighbor. i tried to clean it up by resharpening the image and a slight gaussian blur.
