Replacing images with one of a new size and updating the display size

Permalink
I have been given an new affiliation logo to update on a client's site and the new image is slightly different in dimension. It is in many locations, so I want to use the "Replace" option to update the file. When I do this, it indeed updates to the new image, but it is displayed using the old dimensions, which distorts the image. Is there a better way to update/replace images that will also update the dimensions?
