I use Lightroom Web (lightroom.abode.com) to share collections. When sharing with friends and family I enable the setting that allows recipeints to download images. However, the downloads are very small JPG files (e.g., 370KB). My suggestion is to provide for an adjustabgle setting such that one could permit higher resolution images to be downloaded, e.g., 5MB.
My current soluiton is to send a LR link for easy viewing and a OneDrive link for those who wish to download an image. Of course, this means I need to turn my RAW files into a separate set of JPG images.
Many thanks for your consideration,
