1200 pixels or larger. Any file smaller than 1200 pixels will be rejected. Clients can select different sizes of each image on the site and file pricing is based in part on the image dimensions. Best practice is to upload images in the largest pixel dimensions; we will automatically create all the smaller size files from the highest resolution file that you upload.
Never increase the pixel dimensions of the image to be larger than the original native size.
