EagleEye is the photo App I have looked for!
With EagleEye I can view my photos that are stored on the local SD card by folder (e.g. folder name = Year & Month or folder name = date & event name).
This works even with Android 4.4 and an external SD card (!). ( QuickPic with Android 4.4: “Keine Bilder auf der SD-Karte gefunden!”)
All my photos have IPTC metadata (e.g. caption text) and EagleEye is able to show the IPTC caption automatically together with the photos (if selected to do so).
EagleEye is great for showing photos to a small audience….!
