Just when we thought that we have too many photo sharing social sites already Instagram, 500px and Snapchat proved that it would never be enough! Bring up your original idea, download Dolphin platform with included Photos module, spice it up with Photography-specific extensions and take your chance! Your site could target impressions within your township, or related to specific theme (say, butterflies-only), or concentrate on the very best fashion photographers only - it's your call.
Extensions include photo contests, zooming, galleries, improved privacy settings, enhanced unloaders taggins and even full-blown alternative to Dolphin's standard Photos. Start playing!
