Agree, love this. So far I had my personal geocache image repository on dropbox, but it was always extra work to get the images there. Just pressing a button in Cachly to archive cache relevant photos is great. When I tested this feature and saw how it worked well I instantly "bought" this new version :-)
I also noticed that I could copy all my existing photos (in matching GCxxxxx folders) from DropBox to iCloud drive and they are available in Cachly - great.
One additional thing that would be great: When I have an offline list of my finds on my phone, it would be great if I could filter this list by caches with personal photos.
Best,
David
