Your first link did nothing, but the second ending .jpg is one of three picture file extension types (the other two are .png and .gif). When you reply to a thread, you will see various small squares and the tiny 'Mona Lisa' is used to embed pictures.

LunaPic because Imgur doesn't work with my aging Apple desktop.
