How to select multiple files with a java plugin and then upload with PHP?

[stator]

I am looking a easy way for the user to upload multiple images to the website. The idea I have on mind is like the old Facebook service that, I think, they used Java. You click to add images and popups with a your system files and folders where you can select with checkboxes more than one image, only one, etc.I have never used something like that, and I also didn't touched Java but i think that is the only way to do it.Thanks!PS: I'm not talking about multiple \[code\]<input type="file" />\[/code\].
