How to put a picture from a nikon l830 onto Instagram?

Ok so I'm getting a nikon l830 for my birthday and I really want to upload my pics onto Instagram but I'm not sure how. I don't really want to download any software or anything. Any tips?

* Remove the memory card from your camera
* Copy all the image files to a new file folder named for the subject/location and date (so you can find them again in a few months or even years)
* Using your broadband connection, log on to your Instagram account and upload ONLY the best of the best of those images.
* After you have all your images safely on your computer, insert the memory card into the camera and using the format feature on the camera, format the card.

Do this copy/format process at the end of each shooting day and you will reduce the possibility of ending up with a corrupted memory card.

You do NOT need any special software to do any of the above processes.
