I know modal over a modal is not good UX. But I have a modal window and I am going to place a file upload(browse) component to upload a image for user. I am not really sure, will that break any UX by opening up the second dialog (window) to browse a file? Any suggestions, should I do or do not? Appreciate your comments. NOTE: This is not the modal over another modal, it is modal over a system file upload popup.
