Is not your photo displayed in the thumbnail?

My Friends i have seen that some people have photos on their posts and the first photo is not displayed in the thumbnail.

As for example this one, that I did it on purpose to show them:

This is solved very simply, but most may not know how to fix this problem, and prefer to choose another photo in their gallery.

Just change its name and load it back to Solve the problem, but sometimes the person loses that image and there is another way to solve it.

Here are how to repair them:

Step 1:

We have to get into our Message to modify it, for this we open the Post and we go to the end, where Edit says and click.

Step 2:
Then we go to the url of the first image, and look at whether it has a number at the end of the address enclosed in parentheses.

Just where the cursor is stopped, before the file extension (.jpg, .png, .gif), remove that number from there only, because if we look at the name of the image also has that name, but there That leave it the same.

In this way:

That would solve the problem, finally clicking Update Post.

Update your profile, and that's it!

I hope you have been useful.
Greetings friends
