A few questions perhaps someone knows the answer to:

The hurdle I have is that a client would generally upload a massive image file supplied from their product suppliers. This image file then needs to be resized for large, medium, and small. I'm looking for a way of simplifying that process for the client.

I assume it doesn't resize the image when a user adds it via the add product page. Is that correct?

What naming convention on the images? Original image in different folder, or adding _MED etc etc

When resizing the original large image, does it create a new image with a different name or resize the original?

After uploading an image in add product, then going to image manager is there a way to automatically resize either all or all new images? So that the client doesn't have to go searching for the dozen or so new products/images that he just added so that he can resize them?
