Image slider pagination

So I have a simple gallery but as the screen size gets smaller I change it to an image slider. The navigation buttons on the gallery are square while on the image slider they are round. I would like to make the buttons on the image slider square as well to match those on the gallery. Any idea how?

Another issue I have found with the image slider on an iPhone is that once you click an arrow button it stays on the hover colour even after you have clicked it and stays that way until something else on the page is touched. I would have thought it should change from Hover to Normal as soon as the next image comes up?

Example gallery at bottom of this page.

Bump.

Does anybody know how I can change the shape of the navigation buttons on the Image Slider so that they are square?

The navigation buttons in the Gallery are customisable with a radius function but in the Image Slider the only options are on/off and size.

Currently they are fixed as circular, but I’ll see if we can add a border control to them for the next build…

Thanks. Would be good if they had the same options as the Gallery button.
