Here's a short take on a simple, straight forward photo app for your Windows Phone. Picture Info is an EXIF reader that not only displays the details of your photos but it will also map out where the image was taken if GPS information is present.
For those not familiar, digital image files have an embedded EXIF file (short for Exchangeable Image File format) that contains all the technical data on that particular photo. Data can include camera settings, date and time of the photo, image size, GPS coordinates, any copyright information, etc. The amount of data in the EXIF file varies from camera to camera.
With Picture Info you pull up images from your Pictures Hub and you'll see a thumbnail version of the image and a Detail and Location Page populated with all the EXIF information. The Detail Page with Picture Info will list all the EXIF data available. The Location Page, if GPS data is available, will flag where the image was taken on Bing Maps. You can toggle between street and satellite views as well as launch the Bing Maps app to get directions to that particular location.
I like the simplicity of Picture Info and it's a quick, easy way to pull up data on the pictures you take. Picture Info is a free app that you can grab here at the Windows Phone Marketplace.
