I recently try Dropzone JavaScript library to ease the upload process. It is really a lightweight and good library. I have a existing PHP form that take multiple images, and transfer/upgrading it to dropzone was as easy as include it’s library.

I have little to mention, but a link to site is what I want to include in this post. http://www.dropzonejs.com a must library if you need multiple image upload by user. I use it for a scientific application, where client need to bulk upload about 1000s of image file for database, and it speed up their process. There is nothing much to add for tutorial as their basic tutorial is good enough to start even for newbie.
