NOTE: The service doesn’t seem to be live anymore.
Dropbox’s web interface shows all your photos and videos in one place. However, I find it quite slow while loading the images. In addition, if you are a photographer, you might also want to share your images publicly for others to see. FolioPanda is an online service for turning your Dropbox photos into an website.
FolioPanda organizes your photos in an easily navigable cool layout.
However, the problem I see with this service is privacy. Allowing a ThirdParty app access to your Dropbox or personal photos is never a good idea. So I would recommend FolioPanda only if you have a spare Dropbox account and photos which are OK to be shared publicly.
