Need help regarding writing blog on analytics Vidhya

Hi, Can somebody explain how to add equations in a efficient way in AV blogs or articles? I tried to add .png image but it does not show in the preview.

How did you try to upload image?
Do you upload from local drive or from URL?
Some servers may block images if you URLS to hotlinking

Did you try to use .jpg ?
Did you try to use smaller .png (with less kilobytes)
Do you use some AdBlocker which could block it?

I have no problem to upload (from local drive) and see lenna.png with size 500x500 and 437KB
