Hello,
We are sure that our theme is not the reason of the problem. To check this you can go to Appearance > Themes > activate default Woocommerce theme (Storefront) and check. Probably you made something wrong or did not follow the WooZone plugin documentation or did not use correct plugin settings.
1) We have imported test product and did not face any issues with the images import http://prntscr.com/qq7lee Describe in more detail what way to import products did you use? Maybe provide video for better understanding of your issue.
2) We tried the same params as you had on the screenshot and don’t face any issues with the products search https://gyazo.com/9da4bd997e00050c1c082ce86ac2913e and https://gyazo.com/6425c144ecbed874b25f9d1c50111650
