If you upload images to a originals sub folder you can provide the original images of an event for download. This works both for the new download shipping method and for the download button. You need to create this folder and upload the files manually by using FTP. There is not back end for this. You still need the smaller files for creating the thumbnails. If your server is capable processing the original large files you don’t need this feature. Most webservers are not capable to process your 10MB JPEG files.
