I have been searching (without success) a banner which takes images from product images.
An other options is product slider which shows only image in adequate size.
All tips are welcome.
Normally, the image for the banner slider will be created separately, but not taken from your product images.
So you will find it difficult to look for such an extension.
However, we can custom this kind of module for you.
Please do feel free to contact us to discuss more details about your requirements:
