MetaCard's syntax is arguably more self-consistent with the priciples of
HyperTalk on this one.  Rather than relying on an external MC has native
image objects, with properties that can be querried and set like buttons and
fields.

In this case, the property you're looking for is the fileName of the image
object: 

  set the filename of image 1 to tMyPath
  get the rect of image 1

If you don't already have an image object on the card, you can also import
image files into a new image object using the import command.
