How to move an image in a plugin to the upload directory and make it as a media of wordpress?

I would like to use them in posts.

Expand question:

I would like to generate images using other programs and saved in the temporary folder of my plugin directory.

eg. plugin-name/tmp/image_01.jpg

Then, I would like to upload the image to the upload directory an use it as a media source.

Is that possible?
