This app allows you to search Flickr for photos of all the US national parks. To use the app, select the national park of interest from the combo box listing them. The first on the list is Acadia, the last is Zion. You may choose to download 10, 25, 50 or 100 thumbnails with each search. A tap on a thumbnail will display a larger image to the right, which may be resized with the usual finger gestures. If the owner has given permission, you may download the image to your Pictures folder. The image downloaded will be the largest version available, which is usually much larger than the one being viewed. If GPS was checked when you did the search, you will be able to view a map of the location. In general, there are many more photos without GPS information than with it. A tap on Photo Info will display information on the photo; a tap on the Park Info will take you to Wikipedia to view information about that particular National Park.
The reason for the Most Recent Date picker, is that the Flickr database returns a maximum of 4,000 items. If you had done a search with 100 returns per search and used the Next page 40 times, you would be at the end of the results. To find more you simply change the Most Recent Date to, say, a year or whatever time is appropriate in the past and do a new search with the Page = 1.
The app obviously works best with a multi-touch screen.
This app collects no information about the user and uses no cookies. It does need to have an Internet connection so as to access photos and information about the national parks
It does have advertising to help pay for development since it is a free app.
