Question

Naseer has inserted an image into his document but needs the image to appear on its own line.

Answer 1

I don't know if this will answer your question, however, if using Google Docs, it is as simple as selecting the line you wish the image to be on, and navigating to the insert tab. Located in the INSERT tab, there should be a Image button. Click that, and either upload from the web, or from your device.

Answer 2

Since there seems to be a lack of info

I'd say use the css "display" property

display:block;
