If I put some pictures on my website I can use smart-fields to show exif-data such as the embedded copyright, location, titel, aperture, etc. However when I download one of those images from my website lots of the exif-data, for example the the copyright info and website info, is lost.
Is that normal behaviour ? or is it a setting for the upload I missed or something else ?
Sparkle currently strips any exif from the image when generating the final image that goes in the website. This is for two reasons, one is size/performance of the image, the exif data is rather large, the second is privacy as exif can contain personally identifiable information.
Arguably in some cases the exif information is interesting to export, and we need to add the option to select which metadata to export on a case by case basis.
For the time being exporting an image with exif can really only be done by sharing the image inside a zip file, so processed entirely before adding it in Sparkle.
