    <p>I have been playing with some of the imaging functionality in Java, trying to superimpose one image over another. Like so:</p> <pre><code>BufferedImage background = javax.imageio.ImageIO.read( new ByteArrayInputStream(getDataFromUrl( "https://www.google.com/intl/en_ALL/images/logo.gif" )) ); BufferedImage foreground = javax.imageio.ImageIO.read( new ByteArrayInputStream(getDataFromUrl( "https://upload.wikimedia.org/wikipedia/commons/e/e2/Sunflower_as_gif_small.gif" )) ); WritableRaster backgroundRaster = background.getRaster(); Raster foregroundRaster = foreground.getRaster(); backgroundRaster.setRect(foregroundRaster); </code></pre> <p>Basically, I was attempting to superimpose this: <a href="https://upload.wikimedia.org/wikipedia/commons/e/e2/Sunflower_as_gif_small.gif" rel="nofollow noreferrer">https://upload.wikimedia.org/wikipedia/commons/e/e2/Sunflower_as_gif_small.gif</a><br> <img src="https://upload.wikimedia.org/wikipedia/commons/e/e2/Sunflower_as_gif_small.gif" alt="flower"> <br> on this: <a href="https://www.google.com/intl/en_ALL/images/logo.gif" rel="nofollow noreferrer">https://www.google.com/intl/en_ALL/images/logo.gif</a><br> <img src="https://www.google.com/intl/en_ALL/images/logo.gif" alt="alt text"> <br><br></p> <p>The product appears as: <a href="https://imgur.com/xnpfp.png" rel="nofollow noreferrer">http://imgur.com/xnpfp.png</a><br> <img src="https://imgur.com/xnpfp.png" alt="crappy image"> <br><br></p> <p>From the examples I have seen, this seems to be the appropriate method. Am I missing a step? Is there a better way to handle this? Thank you for your responses.</p>

    2. COI couldn't figure out why they weren't showing up either, until I looked and found that someone else removed them from my post. I added links for the images in case this happens again. Thanks!

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
