Hello, I have read and re-read this entire thread looking for solutions to this problem but to no success. I have followed the instructions on https://i43.tinypic.com/4ida3n.jpg to the letter but it does not work. I uploaded my image which can be viewed here https://guerillamarketingblog.info/wp-content/uploads/2009/07/cateyes.jpg as you can see it is working correctly. When I create a custom field called thumb and use the url for the image as the value then save and update, it does NOT appear on the blog. What is wrong? Please help me!
