Naseer has inserted an image into his document but needs the image to appear on its own line. which option should he choose?

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.
