Macro to change image path

Hi,

I want to make a macro which changes the current JPEG image path with new JPEG image path from one of my folder.

example:

There is one image in my application as one.jpeg with macro code i want to change this image with two.jpeg from folder.

Am working  an idcard generator  where first i get data from excel with print merge then with the id find image from folder and replace the new  image.

An any easy way to do this let me know.
