iOS And XML Image Results Download in the Background?

Hi All...

I'm looking to use the Flickr API search routine to return the latest images for a specific tag. I will probably limit it to the 10 or 20 most recent images. I can create the resulting URL to the images from the resulting XML, and set the file name of an image to that URL, looping through the list of images, but I'm curious as to what would be best practice would be to download these images in the background? Ideally I would like the user to be able to use the simulated swipe routines between the images.

The only thing I can think of is downloading the images in the background as soon as the iOS app is launched. Could a script like this be launched at openStack and run in the background?

Thank you!
