Android ListView image resize

I have a lazy-loading ListView populated with images gotten over the network. The list rows are set to wrap_content, so once the image loads it resizes and the full scale image will be displayed. It looks great when scrolling down, but when scrolling up the rows resize and force the bottom rows off the screen. How can I prevent this jumpy scrolling while scrolling up?



----- EDIT:



The images are comics of varying sizes. Some are 2 or 3 frames where they aren't very tall. Others are single frame comics where they are much taller. The image needs to take up the full width and the height should not cut off any of the comic.
