I have encountered the same problem on Universal-Image-Loader Demo and I hope the Library developers will solve the problem in the next update.
UPDATE: The problem fixed with help of nostra13, you have to update the library to 1.9 version and use this way of displaying pictures in the imageView
:
ImageAware imageAware = new ImageViewAware(imageView, false);
imageLoader.displayImage(imageUri, imageAware);
It solved my problem. Some details of why you should do this can be found here and here
