You can use Batch upload, but you have to manually select each file.

Alternatively, more complicated to set up but much quicker, you can use custom JavaScript (make sure you go to User Preferences -> Under the Hood -> Enable Custom JavaScript). Add this code:

importScriptPage('MultiUpload/code.js', 'dev');

To this page: User:Gundam Legilis/common.js

Then, go to this page and you should be able to select a number of files at once to upload.
