Using Barcode to open image with same name

Hi Guys

quite new to this arduino stuff. I have combined two codes i have found online one for loading bitmaps from sd to screen and another on how to view barcode news. I was just wondering how do i use the barcode number scanned to open the image with the same file name? attached is the code i have so far.

So, what does the "LOOP()" do when you run it?

Does it ... function as expected? Does it ... display anything or nothing? Does it ... blink the LED?
