Upload your image to dropbox or similar and share link. Also, you can use Lightshot Screenshot extension to share your screenshots.
1) We can’t reproduce the issue but I suppose that lazy loading of the element may be the reason of the issue. I have disabled this option. Try now and let me know if you still have the Ajax error.
2) That element displays the Categories + subcategories by default and if you set limit you’ll get the View all link. Use Product Categories element http://prntscr.com/n0eph4 instead of the Product categories list.
