What about these rules do you think is confusing: 
# 5 text lines max at 600x800 screen size
# Optionally 3 text lines and
1 image
# Text size is limited to "size=1"
# Image size will be limited to 150K
# Image will be limited to 150H X 500W pixels
Take the time to combine the 2 pics and text into one jpg that does not exceed the signature rules.
Think of other members/users that waste connect time loading your signature.
