He's right that is pretty old.
Try this link...

follow the instructions "Adding this PPA to your system" to upgrade to
gambas 3.16 stable.


But you will probably find your issue it the container/panel your picture
box is in.
It takes a little experimentation to make sure your picture box is not in a
panel that will stretch the image even if Contain is set.
try setting the parent panel Arrangement to Arrange.None and Expand = false.
If you are not sure if it is the panel shape set the panels background to a
temporary colour to highlight it's shape.

Best of luck
