Image hosting service
A host of images allows users to send pictures and images on a computer server to easily share with family and other users.
How does it work?
Usage is very simple: after uploading the image, the user has the choice between several codes ready for use (copy paste) by destination and use of the image.
These codes are generally available as a link (x) HTML and BBCode (for most forums) or as a thumbnail linked to the original image.
The economic model of hosting image often means that they offer this service free to users in exchange for advertising displays, for the funding (these are advertisers who pay for the hosting).
For those wishing to share their works, the host manages the Flickr user licenses photos, which you can then use free (or not) hosted images.
