All Shows on Screeners.com require two key art images to publish - a Large Banner and Show Key Art.
The Large Banner will be used as the show's thumbnail in the Screeners main view, as well as a background image for the Episode gallery.
The Show Key Art will be used as a thumbnail in New Show notifications.
You can upload .jpg or .png files of any size, and crop or resize them using the Art Resizer after uploading:
Individual episodes require custom thumbnails, called a Poster Frame, which will also be the image used in New Episode notifications. Again, these can be uploaded as .jpg and .png files of any size and cropped using the Art Resizer.
