A new piece of "background software" has been added that automatically resizes large images to 2000x2000 pixels or less. This gives users the ability to upload larger images without paying any mind to constraints, but keep in mind that huge pictures will still take a long time to upload. Once the pic is posted, it will be a reasonable size that anyone should be able to load quickly. Lagoon Nebula image, 4000x2735 automatically resized to 2000x1367
