Yeah, I don’t think the “support” is all that it’s cracked up to be unless you pay for the upgrade.
I’ve been cropping the images I upload to the media library so that they look good on the slider. Unfortunately I haven’t figured out how to make them also look good in preview image below the slider. Not sure if this is called a thumbnail or not. I tried cropping the images within the media library but have yet to figure out which images this impacts. Oh well, another WP theme that is wonky, it looks good enough I guess..sigh.
