Hi Kid,
Create an array for each category
either manually or by reading from the directories ( better keep each category images in separate directories )

Now assume that you have the following arrays
which contains all image urls in that category

$love_img_arr,$bdy_arr......

Now select random image from each category

mt_srand((double) time()*100000)

$love_rand_num=mt_rand(1,sizeof($love_img_arr)-1);
$love_img_src=$love_img_arr[$love_rand_num];
$bdy_arr_num=mt_rand(1,sizeof($bdy_img_arr)-1);
$bdy_img_src=$bdy_img_arr[$bdy_rand_num];

.................

Hope you follow
