From the pics I’ve seen of that game it looks more like the horizontal/vertical coordinates of the objects are changed, not the size. Positioning an object up and down happens by changing the y property. Positioning an object side to side happens by changing the x property.

so what code would you recommend I need help
It kind of sounds like you’re trying to bite off more than you can chew. If you’re a Corona newbie (I’m guessing you are) you might want to get some foundation before trying to make a complete game. Even if it is a simple one. 
There’s a free video crash course here: http://masteringcoronasdk.com/game-development-crash-course/
You might want to go through that first (only takes an hour or two) and see if that helps answer some of your questions. It does cover positioning objects on the screen as well as simple animation and sound effects.

I know sprites I know sound effects I know a lot I just can’t grasp random images.
You really need to go back to basics. Without knowing about tables, positioning images on the screen, etc you’re not going to get far before hitting another road block.
Once you know how lua works, and what APIs are available, everything else is just a question of applying logic to each problem.
I know about tables and I know about positioning images…
Do you know about enterFrame listeners, display groups, scrolling, conditional logic, touch listeners?
If you do, then you have all you need to write flappy bird. If not, you’ll need to read about those things.
I know all of that I just don’t have the math.random part nailed
