i have made my own siggy and have its dimensions at 700 x 150 at 72dpi-- the file size is over 500 KB-- can someone tell me what i need to do to reducemy file size to get it under 30kb? i am using macromedia suite and/or Microsoft Digital Imaging Suite 10. i did resize on Microsoft program and it only gives me pixel size, dpi and image size as options i can change.
