243,266 PointsIt looks like you've created a "visual loop" with your event handlers and positioning. By placing the images over the input, when they appear under the pointer that will cause a mouseout event for the input element. Then when they are removed, a mouseover event will occur for the input again. You can demonstrate this by keeping the pointer away from the images as you move it in and out of the input area and you won't have the flickering.
An easy fix would be to position your image elements so they don't overlap the input element. Otherwise, you might need additional handlers (or a delegated handler) and code to check if the pointer is still within the bounds of the parent element before doing anything to the images.
