Viraltag is a simple application that lets you manage all your pictures on one single interface, whether it's for Facebook, Twitter, Tumblr, LinkedIn, Flickr, Picasa, or Instagram.
You can post instantly, or schedule them to be posted on a specific day and time. You can also edit the text in the descripitions and choose which account you want to post them from. This can be especially useful if you manage an account for a business and have to schedule posts for a specific time or to be posted on the weekend.
Furthermore, Viraltag lets you discover new content from other users, through the Discover tab. There, you can find categories you can share with your contacts on the social networks you have linked with Viraltag.
