2. Raster Graphics
• Raster images are made of bitmaps. Bitmaps
are an image that have a fixed resolution
(resizing them can result in distortion).
3. Vector Graphics
• Vector/ path images are created by choosing
where a path starts and ends using
mathematics. Paths can become shapes like
squares, triangles and curved shapes too.
• Vectors can be scaled big and small with no
loss in definition. Perfect for logo transitions
from huge billboards to small business cards

17. Optimising
Why would you optimise? Optimizing ensures easy viewing on the
web.
How can you optimise? You have the ability to save images as
different types of images. You can also
change the resolution of images to make
file sizes smaller
Advantage to optimising Because images that are uploaded to the
web when they’re not optimized have a
large file size, causing downloads to take
longer. Optimizing makes images quicker
to upload and download.
Disadvantage to optimising Images should not be more than 500 pixels
wide.
