i'm looking for a jquery plugin that can upload multiple images. I've tried uploadify and it works well.
But with huge images it's very slow.
is There anything like uploadify that resize also the images before upload them?
thanks
Checkout http://www.plupload.com/

It was just released a few days ago (3rd Feb) and has the functionality you are looking for (Client-side resizing and chunking specifically can both improve performance).
It's core isn't based on jQuery, but it has a jQuery upload widget that's plug-and-play.

Won't dictate your design, very flexible. Does not do multiple files (yet), though you can post multiple times from the same page w/o re-directing the user anywhere. It has a lot of options. Again, it's designed to fit into your design, so here's a demo that barely lets you know it's done with Flash because of all the JavaScript integration it has: http://www.shift8creative.com/projects/agile-uploader/advanced-demo.html
For use with any back-end language.
Use Flajaxian, its free and works with S3
Latest version of SwfUpload does client-side image resizing (using Flash), but it's not the easiest script to use.
There is Uploadify image resize before upload extension. Check http://perfectwebtutorials.com/2012/image-resize-before-upload-uploadify/
