An app named Gallery Excluder has been created by a  XDA user, knox420. Its been quite a while since we have been hearing that most of the people are having problem with their gallery in that unwanted images show up from other apps that are installed.With Gallery Excluder you to select any folders that you do not want to show up in your gallery.Its very a easy and simple interface. Just check the folder and click the menu and “update media gallery.”

Though one the problem I have heard is there is no way to check a subfolder for excluding images. The app will be soon released.
