The software works with any digital camera and GPS
All digital photos and all GPS-collected positions contain the common element of date and time.  GPS-Photo Link software uses this common time element to "link" digital photos to GPS positions. 

GPS-Photo Link generates
1) watermarked copies of the photos displaying the coordinates of the photo location the photo and other attributes, 2) ESRI shapefiles or a geodatabase feature classes for display of photo locations and hyperlinks to the images, and the management of digital photos spatially, and 3) for non-ArcGIS users, other GIS formats such as .mkml for Google Earth.

A camera with onboard GPS is highly recommended since the gps coordinates and custom attributes entered via the camera back are written directly to the digital image file as the photo is taken.  This greatly simplifies getting processing and file management.  There is no longer a need to synchronize camera and GPS time.  It also eliminates the need to fret over which camera files go with which GPS files - a serious consideration with multiple teams, field sesions or pieces of equipment.  

ArcGIS is not necesary to use GPS-Photo Link.  The software produces Google .kml files and and other common GIS formats.
