I'm unable to get a modified button from a .zip or .bmp file to the gallery. In the ultimate pronto guide on page 86 it tells you that " These buttons are then ready to be pulled into your favorite .bmp editor and modified, or dumped into the gallery, under the tools menu." I'm only able to get buttons from an open configuration with the insert button. Please help. Thank you, Mike

A button has two images - for pressed and released state. Add a button then change the image for each state. Then you can put it in the Gallery.

Most of us do not bother using the Gallery - once you have it in your configuration you can simply copy it as many times as you want within the configuration.
