12 IMAGES
From the ‘Worked’ folder, open the image remora.jpg in your
graphics manipulation package. We have chosen GIMP for this
task. Select the Rectangle Select Tool and use this to lasso
the image of the remora. Before changing the image size check
whether the Fixed drop-down menu is set to Aspect ratio.
saving. This is one method of reducing the colour depth of an image. If you look
at the files remora.jpg, remora1.jpg and remora2.jpg, you should see their sizes
have decreased with each stage.
In GIMP (and many other packages, such as Adobe Photoshop)
images are resized using the Image tab, followed by Scale
Image….
This opens the Scale Image
window. To set the image
width to 80 pixels, change
the value in the Width: box.
There is no need to enter
a height as the image will
maintain its aspect ratio
as this had been fixed. To
change the image size, click
on the Scale button.
This will alter the size of the image within the package like
this.
Advice
To intentionally distort an image you would fix the new width
(or height) using the Fixed drop-down menu and enter a height
as well as a width for the image.
To save the new image as a JPEG file, select File, then Export
As... and enter the new filename remora1.jpg before clicking
on Export. As this image will be saved in JPEG format, you
are given options on the image quality that you require. These can be
selected using the slide bar or selecting from the drop-down menu.
1 is the smallest file size that you can have, but also gives the poorest
quality images. 100 is the highest quality, but results in large file sizes,
which are much slower to download over the internet.
Resampling an image
This process of changing the image quality is called resampling. Images
can be downsampled, meaning fewer pixels are used for the image, as
you have just done by reducing the image quality. Images can also be
upsampled by adding more pixels. Downsampling reduces the file size and
therefore makes the web page load more quickly. Export the same image
again, downsampling the image by lowering the resolution (quality) when

be possible to tell that you have placed the image
correctly as it has a white background. A good tip is
to place a thin border around the image so that its
alignment can be seen.
To set a border on the image, click the right mouse button
on the image and select Format Picture from the drop-down
menu. This opens the Format Picture pane to the right of
the document. Click the left mouse button on the Paint
bucket icon to select the Fill and Line section of this menu.
Click the left mouse button on the triangle for the Line

Left click on the radio button for Solid line, which again
extends the options in the pane. Choose a (thin) line Width

Click the
button to place the image. Check that this

being placed with too little precision when it was dragged
and dropped. Try dragging and dropping the image again and
