ImgScan Control create a big file size

hi
when i create an image file (bmp or jpg) with the imgscan control
from my vb application i get a very big file size (between 300 - 400 kb)
how can i create smaller file ,when i scan from a vb application

thanks

File size for Images is directly proportional to the resolution of the image... number of colors also has a big effect. Try reducing the resolution and/or number of colors used.
