Scale Images to different sizes

Hey everyone. So I have an issue. I am trying to get my experiment to function appropriately. My goal is this: I need to present participants with an image stimulus (32 different images in a row). Each of my images needs to be a different size. Now, I am not good at coding at all. I had it functioning in the builder adequately but then it just stopped doing it all of a sudden. If there is a way to set the “size” variable in the builder to the size of the presented image I need to know. I had it set at one point and it was working, but now it is not.

Edit– I got the images to appear and size correctly, now however, my images are mirrored (even though no mirror options are enabled. Is there any way to get them to be normal?

Thanks
