open the bmp file - edit - define pattern. open the file you want to flood.   ' edit ' -  ' fill ' -  a window will pop up - scroll down the "use" scroll down menu, lick - ' pattern ' click the custom pattern button and click the tiny preview of which one you want.

to ensure this addition stays on you computer - while you have the prieview window open the arrow to the side.. ">"   and  click ' save patterns... '  hopefully it takes you to the right folder where the rest are kept. it won't save the individual fill pattern but the entire set of patterns.

i'm not too comfotable with turning .jpg to .pat just by renaming a file name in windows, in this cenario it won't work
