How to upload / resize images easier?

Hey folks,
I´m looking for a tool to publish pictures more easy. At the time I have to

1. choose pictures from my harddisk and save the filename (with right-click, properties, mark adress, copy)

2. resize them manually with paint shop to get photos of the size here (normally they are huge, as thumbnails they are to tiny to understand)

3. go in the wordpress interface

4. insert the pictures (upload, wait for the editor, wait for the popup, insert manually)

That really takes time. How do you do that? Isn´t there e.g. a fine plugin that automatically resizes the pictures I integrate?

Thanks for every idea!

David
