• When you have a lot of images to upload at one go, and not necessarily if they're from the same team, please do so using the upload pack function instead of individually. While there is a limit of 6 individual images to be uploaded per person, there is no limit to the amount of packs which can be uploaded, each of which can have up to 50 images included.
