Present an image with background
In my experiment I would like to present small image, in the middle of the screen, with a background of a different image (e.g., a cat in a background of forest).
I did the same in my last experiment but it contains a word with a background and not a pic...
In addition, i have 50 images to present and i would like to mix between them and do not build a sequential presentation.
How can i do it? How to define the images and use them in my loop? I succsfully defined the backgrounds' images but not the stimulus' images.
