I am aware of memory and processing issues relates with huge photo files; disk space is not an issue, but processing load could be.
Most users will he happy with 1000 x 800 or 800 x 600, so it makes sense to limit the viewing size. But we occasionally use those photos for high-resolution printing @300
dpi in CMYK... and they are huge files (15-20 Mb).
Ideally, I would like to keep both versions linked in a certain way, as these 5-6 users are not in office and searching photos with Zen is simpler than in a generic file system.
So what would be the best solution ?
1. Load the extra-large photo and not worry about it? IOW, is it manageable on a good shared server? And is it a wise use of resources?
2. Reduce resolution manually. Then upload both versions in Zenphoto. Where / how would I load them so that Zenphoto considers them as 2 resolutions of the same photo?
3. Load only the medium-size photo in Zenphoto and store the hi-res in a (password-protected) folder outside the gallery? Could I have insert a description line like "download high-res photo at http:..." and make it so that only users with the need for high-resolution images would see the link?
P.S. Maybe some of that is in the documentation. If so, could anyone point me in the right direction?
