Timeline Display: Advance each image individually with white Right/Left arrows. Click the small double chevrons in the thumbnail timeline to rapidly advance the thumbnail photos 10 images at a time. Hold the double chevron down to slowly crawl through these images.

Grid/Browser Display: Sort through the grid to view a series of photos you have identified into a group.


Every image is (or is in the process of being) categorized according to our 39 controlled "category tags"; the more detailed tagging is up to you. Log in and tag what you see in a picture: horse, corn, bridge, park, picnic...whatever descriptive terms you think will help others find a photo. Tags are vetted, so please tag responsibly. Some words of advice: Be specific and descriptive and think of what people might be inclined to search for. If the general category term is "animal" then a specific, descriptive term someone might search for is "goat" or "racoon" or "dog." Do not tag what you feel; focus on the details in the image. However, if you are too detailed, like “old Methodist church” no one would ever think to search for that term.
