The value will be myImage.img. Here's the reason why. getfield works like this:

 

 

{field1}{sep}{field2}{sep}{field3}{sep}...

 

 

For your URI of

 

 

/myImage.img

 

 

If you use a slash ("/") as a separator, then the first token will be before the separator and the second will be after. So the field number "1" would be what's before the slash (an empty string) and the field number "2" would be after the first slash (myImage.img).
