Draining batteries can be a significant issue with some cameras.   After a few tries with my first digital p&s with manual options and a whopping 4mp, I got a card reader.  That makes it really easy if you have a place to put the images when the card is read.

My method is simple to upload...but I got into my method of workflow, too. Sorry, that was not the issure in this thread. There are likely easier ways.  

Still, I would not go back to upload from camera.  Also, with some cameras and cards, if you delete an image from the card via the computer, the cards can do funny things. So, all my in-card deletes are done with the camera, generally a format when the care info is all saved and backup made.
