We have increased the maximum file size that you can upload via our website.
The maximum upload size for a single image is now 225 MB which allows you a maximum pixel dimension in excess of 30,000 in width or height, files exceeding this number of pixels will be rejected by our online system but we can organise prints for these files in a different way, just contact us for more information.
Remember that you should upload your files in JPEG (recommended) or TIFF with LZW compression. Visit our support section for more information on preparing your image.
