I would a quote on a mod made up for open cart v220.127.116.11+
Using the nivo slider as there are some out there but not like this for open cart
I have made a short screen cast to explane what I am after you may need quicktime to view.
Also to have options to be able to change height and with some where in admin.
Min requirement experience of open cart is 2 years
Would be a good item to sell on open cart extensions.
