Image not appearing on screen

I have a conditions folder. In that conditions folder is another folder named Image. In that folder are my stimuli. In my conditions file is a column titled Image_file with my stimuli in it written as image/example.jpg but when I run my experiment I only get a white screen instead of my stimuli. In the Image field of my image component I have inserted $Image_file. Can anyone tell me why my screen is still a white background, and not my stimuli? I have fiddle with the size a bit but when I make it smaller it just becomes a white background in a gray background. Any advice? The stimuli I put directly into my conditions folder show up fine, but the ones in their own image folders aren’t showing up. I need them this way because those stimuli should be different after each repeat.
