ios - Building a flickr app on iPad -

i'm building ipad application needs display cluster of pictures flickr.

each cluster (group) can have 10 or 100 pictures. when app starts, can see first 10 clusters (kinda groups of pictures, such in "photos" installed application (if pinch group, see pictures inside it).

now, question performance, , how retrieve pictures flickr. i'm considering subset of 300.000 pictures, approximately 2389 clusters , i'm going load needed on screen.

when apps start should load pictures included in first 10 visible clusters ? (please note cluster represented bunch of ids, way display stacking included pictures, in same way photos application does).

should use uitableviewcontroller ? have no clue apis use, need help.

thanks
