how to make an article that only appears on mobile site

My main site has a picture gallery that does not show on mobile site. I was thinking if I made a new article with just a column of images it would show the images on mobile joomla in a user friendly way. How can I make this article only appear on the mobile site? Thinking of making an uncategorised joomal article and putting it in a placehere module and assigning it to a mobile module position that doesnot appear on the main site.

Or if there is any other way to show a series of images on the mobile site. Please help. thanks Frankie

Frankie again. I just tried my way above with the place here module - it nworks and shows the images in a column but it means that the images appear on every page or do i need to make a new menu item for the new photogallery.
