display image and text when image uploaded

i'm stuck here for about 2 days.

i have images and texts to display to people as a result of when they upload their pic in my input box.

i want prepared images and texts to be shown to them as a pair but it should be picked randomly in the pool.

So, simply saying,

1. people upload their pics to input box.

2. one of matched image and text in the pool randomly to be displayed them as a result.

please let me get out of this cobious strip, please.

thanks.
