Why is the image size limit 6 MB?
We have accounts set to 6 MB by default as to discourage users from regularly uploading very large images, as most designs don’t require images larger than 6 MB. Large images can make things run slower for you/your customers. Additionally, if a design is too large, the server will fail when it is downloaded and will instead be emailed to your customer. The file is usually emailed within minutes, but can take up to 24 hours.
If your designs require images larger than 6 MB, please contact support and we can raise the limit for you.
