Displaying small pictures in a text window

I want to display small pictures in a text window, its actually emoticons in
a messenger I want to implement. How should I do this in Java. Ideally I
would like to support animated pictures, but any method to display any
format would be welcome.

Thanks
Allan

Thanks,

Can I also change the colour of fonts with a JTextArea? I had a look but
couldnt see how. Is there a way to have changable colour fonts AND be able
to add the pictures?

Many Thanks
Allan

with JTextPane you can many things.
some important keywords: setCharacterAttributes, setParagraphAttributes,
AttributeSet

Actually, there is one last thing - I might be pushing it here! What if I
wanted to add a background image instead of the plain coloured background.
Do you know if this is possible?

Thanks
Allan

probably you could create your own BTextpane
and override paintComponent as follow:

public void paintComponent(Graphics g) {
paintBackgroundImage();
super.paint(g);
}

Yes, is the usual way. see http://mindprod.com/jgloss/jtextarea.html
but everything must be the same. If you want variety, you need a
JTextPane or JEditorPane.

I have this implemented now, however some of the animated gifs come out
slightly corrupted, in that a few of the frames are wrong, or they only show
part of the file - is there anything I can do or should be doing to avoid
this?

Thanks
Allan
