Hi,
I would like to answer your questions as follow:
I want to use it in the t3 blank template, so which slideshow profiles and skins are responsive?
>> We don’t have overidden style for JA Slideshow 3 on T3 blank template. You need to customize some css styles to make this module responsive. And there is no profile/skin of JA Slideshow 3 responsive on T3 blank template.
Also how do you size the images from the K2 component?
>> When your upload an image in Image tab of New K2 item, the image will be resized to thumbnail image automatically.
But, you can control the image size on K2 item in Components >>K2 >> Items >> Parameters >> Images tab.
Could you possibly supply the profile and skin from JA Brisk?
No. We don’t have profile/skin of JA Slideshow 3 from JA Brisk template.
On this template, we use JA Slideshow lite module in default layout.
