a big drag and drop area (although the whole page will be file drop zone)
After a file is selected. The drop will reduce to half and it will show the list of files.
The list can be very long (assume 100 images)
A cross button on the right side of the file. (Once click it will remove the file. I am working on this algorithm.) so just place a button there.
A progress bar on the bottom of every item on the file list. It can be a simple div with any background. That will stretch from 0 to 100% of its parent width. Please use minimal js to create this animation. (add animation to width ig) because js will update this once the bytes are sent to the server.
The following properties are needed on that page.
