Hovering multiple images over one quad

i’ve a pretty huge picture stripe, that im moving around
there are multiple layers of the stripe, also video and alpha png picture sequences

its working so far but the performance is a problem

just rethought if there might be a posibility, of not moving a stripe made of quads around, where just one is in the focus(viewable area), but hovering different textures over the quad

its not wokring to go with a cons of multiple texture files in the texture of the quad and transform the texture —

will always be the first texture …

any suggestions

thank you
