Instagram is the site which allows the user to share and upload their images which can be further expressed liking by clicking on the heart button . the image social networking site has the security which doesnt not allow anyone to savfe the images but however their are apps available which helps people to save their desired images either by screenshot or direct url download. the website is mostly used by app on the phone as most of the images uploaded are selfies and this webiste brought out the trend for taking selfies . we can directly message anyone we want ot alk to . thier are random images posted as it can be seen in the timeline as the user has liked the pages or persons. people can follow eachother to acces the images or details of the other user. just like a friend added up in facebook. now instagram has added the video cliping feauture which replaces the use of snapchat so people now dont have to use snapchat anyomre. I use this app for images and mostly it is used by girls as they are obssessed in taking their pics.
