dragdrop ui position absolute

dragdrop ui position absolute

I have a button which adds new image elements to a page at a fixed location (left: 132 top: 0). Each new image will sit on top of the last one unless the user moves it. If the user clicks add image and moves the image then clicks new image again both images are movable; however, if the user clicks add image twice then tries to move the top image, the bottom image cannot be moved unless the top image has been deleted.

I attached a quick example to better explain the situation. In the example, the image with a border around it will be deleted when the user clicks delete image.
