The plugin affects the uploaded image while it is uploaded. Straight 
after it is uploaded, it it resized physically to the given width. 
There is no original image left, nor made a backup. Also EXIF infor- 
mation is lost.
A lot of WordPress users or developers who use WordPress as a CMS 
and want to configurate it for easy use, would like to have an option 
to resize uploaded images. Some images come straight from digital cameras 
and exceed 4000 pixels in width. So it would be nice to reduce that to 
the max width you use inside your WordPress theme.
If you want to keep control about perfect sharp and resized images, you 
better use photo editing tools on your computer, not a script like this.
The plugin uses a class originally from Jacob Wyke (www.redvodkajelly.com).

Resize at Upload

This plugin resizes uploaded images to a given width.

Bulk images allows you to optimize images uploaded to wordpress without creating unnecessary copies of the upload folder!
Warning: the plugin overwrites images. 
Later the plugin tries to update links to images in articles and metadata, but it may happen that these need to be recreated. Other plugins that optimize images generally duplicate all images and create complex overlays to manage their systems. This plugin is designed to keep sites with the original wordpress structure, but it may require a little more work later. But I believe this work is rewarded by better final quality. 
If anything goes wrong anyway you can go back with the restore button.
