    How do I alter this code so that text is stored in a String variable, and all images are stored in an image array? Anything helps, thanks.

    You don't. You inspect the contents of clipboard for the best way to retrieve it, for example..

    Selecting all the contents of a web page and copying it, then running...

    Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
for (DataFlavor flavor : clipboard.getAvailableDataFlavors()) {
    System.out.println(flavor);
}

    produces..

    Now, you need to pick one which will be most useful to you, maybe something like...

    try {
    Object data = clipboard.getData(DataFlavor.allHtmlFlavor);
    System.out.println(data);
} catch (UnsupportedFlavorException | IOException ex) {
    ex.printStackTrace();
}

    Which just happens to return a String representation of the html/text content, because, lets face it, that's all a web page actually is.

    You'll need to parse the page for appropriate resources and download them manually
