Three20 Image Gallery - Shows Oversized Image, Then Focuses

I have used the Three20 Framework to setup an image gallery in my iPhone App. I am sending in the specific width and height for each image, but when I view the individual images, they load at a slightly oversized size, they are a bit pixelated, and then they focus down to the correct size/ratio.

Most of the images are 300 x 400 and I am sending in 300 x 400 and the width and height, so when I view in landscape mode, I would expect the im开发者_高级运维ages to appear smaller than the overall screen, or to size-up to fill the screen.

Any ideas why I am getting larger images that size-down after they are fully loaded?

if you are in landscape and passing 300x400, then it loads the image at 300x400 then does the scale to landscape (which is 480x300 max possible) after it has loaded completely (and therefore the controller knows its size from the image itself).
