Writing beside image

While writing an article, I create a block for image and put an image, still, lot of space is blank on the side of the image. Then, I create a block for paragraphs and write text related to the image. So, image and text are one above the other.
But, actually, I want to start writing in the blank space on the side of image.

I am not getting any solution how to do it. Pl advise.

Thanks
