Just download this component + module for Joomla 1.5 and it's a nice extension for banner management, and above all.... its FREE.
Also there's already banner size presets which make it even easier to use.

Small suggestion:
make another documentation with pictures in it for beginner user on next updates.

Thanks to the development team for making this excellent extension free.

Just found this J 1.5 version, and it's working perfect!
I've try to use the legacy one but it doesn't work.
Thanks for this great plugin!
