This picture represents freedom/independence.

"I am no bird; and no net ensnares me: I am a free human being with an independent will" (Bronte 284).

          Jane has desired for freedom since childhood. She proclaims a desire to be as free and independent as a bird but, she makes it very clear that she is not a bird within a snare. Her declaration here means that she is in fact an independent human being with choices and free will. At Lowood, Jane gets bored doing all the same stuff, and she doesn't like being caught at a single place for years. She longs for a new place and desires for liberty. To get out of Lowood, Jane advertises in a newspaper which is very independent for a woman to do at that time. It was very rare for any woman/governess to advertise in newspaper since woman were not supposed to provide for themselves. She doesn't like to be controlled by anyone. Although Jane loves Rochester, she does not do what he wants her to do. Rochester wants her to stay with him but she does not think it is right to stay with him and therefore, she wants to leave. Later, Jane does leave. Jane has her own morals and once she decides to do something, she sticks to it. She does not let anyone convince her and make her do what she does not want to do. However, she does let St. John control her at some point. For example, St. John makes her learn Hindostanee. She is not willing to learn it but she has to since he is the one who saved her from dying. Later in the novel, Jane marries Rochester not because she needs a man to rely on, but because she loves him. She marries Rochester, a guy who is twice as old as her. She does not care what people would think about her, she does what she wills to do. Therefore, Jane is an independent woman.
