Image Order

I have a custom post type that calls in the images attached to a post without actually using the wordpress gallery feature. So far it seems to display the posts in the reverse order they where updated. I have tried adding the code 'order'=> 'ASC', in various places and I keep getting errors. Would someone mind advising if I am going about this the right way and if possible help me fix the code to display the images in the order set in the media section of the post or advise if I need to get my post code redone to use the Gallery plugin?

Many Thanks

James
