I think that many habraradi remember the evolutionary stages of the development of photohosting.
In those days, when a digital camera cost thousands of dollars, the flatbed scanner was an expensive, slow and inconvenient device, the average Internet user was not a 16-year-old girl, but a 25-year-old engineer, the very meaning of photo hosting was vague.
Later, the above-mentioned equipment became more accessible, users had a need to post their photo shoots to the Internet. Began to appear the first sites providing this opportunity. Photo uploads were single-piece, disk quotas were microscopic, and the interface was primitive.
Soon the web2.0 bubble began to inflate.
Flickr ,
Picasa and other beauties were born. Interfaces have become more humane, disk quotas have increased, convenient multi-loading files have appeared.

The boom of social networks has come. Users were given the opportunity to mark each other in photos (
Facebook ,
Vkontakte )
Today, the effect of frustration of the user in social networks began to appear, and in order to keep the user, social application platforms such as Facebook, MySpace, Open Social were invented.

Photo Plus - an application for Facebook - is an attempt to take another step in the evolution of photohosting. We decided to adopt the best of our previous experience and introduce new features, such as
Combining photos from different photo services in one photo gallery. Now users of Flickr and Picasa will finally be able to mark each other in the photos.
As a tag for photos, you can now select different images, and not be content with just a gray frame.
Comments to the photo can be tied to the tag. In this case, they will be displayed as a
speech bubble.
A photo gallery reminiscent of
Itunes Coverflow . This simplifies navigation and makes it more attractive.
In our plans, porting applications for MySpace and OpenSocial.
