Submit Your Images

Image Submission Specs

When you submit your images they must be:

• Resized to 4000 pixels on the long side at 72 dpi
• Using sRGB colour mode
• High quality JPEG (90-100%)
• You can watermark your images, but this should be discreet (we suggest in one corner)

We want your images to look their best, so if you need assistance in preparing your images, please follow the resizing and exporting instructions on the Prepare page.

Images may be re-submitted as many times as you like - the most recently submitted image will always overwrite the previous image. Just refresh the page to see the most up-to-date submission information.
