Paste an image to replace an existing one

[teshurtz]

In ms office 2003 when you did a paste function with an image, when a previous image was selected, the old image would be replaced and the old image's size and position would be applied to the new image. In 2010 it just pastes the new image wherever in the default size and retains the old image. How do I make it work like it used to in 2010. I have lots of images that I sized and positioned and now need to be updated to new images and I would prefer to not have to re-size and position them all again individually. Also I don't want to have to save the images individually, just copy and paste from another office product (specifically right now I am pasting excel charts as images in a power point slide but would like to know how to do it in general for other office programs as well.)
