Create upload function like Google Drive/Gumtree

I need a method like in Google Drive/Gumtree where user can drag and drop the files onto the browser and the browser will upload the required file to the server. Also need an animation like the Google Drive, like this: [login to view URL] When uploading, there should be animation to show the progress in percentage. The control will need to validate the file format and reject the file if they are not in the correct format. For example, if set to only accept *.jpg and *.bmp. Dragging any other file format will reject it and show a message.
