In the past few days, I faced a problem with image thumbnails on Blogger. Thumbnails were not showing in the Popular Posts widget, Recent Posts widget etc. Here is what you have to do if you are having the same problem.
Go to the “Edit Post” of the post for which thumbnails is not showing
2. Make sure you are on “Edit HTML“. tab
3. Find the image’s url. The url would look like this
Simply replace https://lh4.googleusercontent.com/– with http://lh4.ggpht.com/- and your’ done.
New url should look like this
I’m sure Blogger will fix this problem soon but before they do, you will have to do this for every post if you want thumbnails for your images on your widgets
