here is my scenario

i have a website where i redirect my users basing upon the device they were using, lets say a user is visiting from an iPad, i take him directly to the page of iPad wallpapers, the user selects iPad version & i take the user to the gallery of wallpapers where the user can select & download any wallpaper. Every wallpaper is the required resolution, i have my reasons for doing this,

now the thing is there are diff. resolution. versions of an image appearing one 5 diff. sections of my website, each having their own view page

Now there is only one record in db.table for the image, and basing on the my consistent naming convention of the images, i pick the required image.

this means when 5 different pages are generated in 5 categorized sections of the website, due to a shared DB record, the keywords, the titles and every single detail of the 5 pages is same besides the resolution of the image, and the section specific details that the page has and yeah the pages also have different paths like

wallpapers.com\ipad-1\cars\Ferrari-dino.html
wallpapers.com\ipad-2\cars\Ferrari-dino.html
wallpapers.com\ipad-3\cars\Ferrari-dino.html
wallpapers.com\ipad-4\cars\Ferrari-dino.html
wallpapers.com\ipad-5\cars\Ferrari-dino.html

now this is my scenario, How do Search Engines see it and how do they rank it? Is it a Good or Normal or Bad SEO practice? If bad how dangerous it is for my sites SEO? i need your comments on my scenario.
