Make a Gallery Intent of a Specific Folder

Question

I am trying to initiate a gallery intent, but I only want it to grab photos in a specific directory.. From a different post, I received this code:

Intent intent = new Intent();  
intent.setType("file:///sdcard/Pictures/*");  
intent.setAction(Intent.ACTION_GET_CONTENT);  
startActivityForResult(intent,1);  

But it's not working.. Is this possible?
