Hi There - I've searched for this but can't find the answer yet.
I'm using the angular theme (great theme BTW) and when I add a new portfolio item - the thumbnail it generates is poor quality. It looks slightly low in resolution. The image for the actual portfolio item is fine when you view it but it's just the thumbnails are not so good.
Please advise how I can fix this? Is there a particular image size dimension that works best (currently all my images are 700wide with varying heights depending on whether it's portrait or landscape).
