Images not displaying

I built my website on MAMP and then when I moved it over to a subdomain on the internet, it displays a questionmark(under Safari) where the images should be that were added via IMCE. When I click to add image, I can upload image but the IMCE browser displays a questionmark on the image. When I log into cPanel I can see the image did upload perfectly. When I view the website in Firefox then it doesn't display any image that was added via IMCE. I've checked every setting I can think of but still can't get it working. Screenshot attached.

Please help me.
