What is the difference between .JPG and .SWF images?

_________________________________________________

.JPG images and .SWF images are two types of images.  It is important to note that it is possible for a .SWF image to contain .JPG images, but not the other way around.

.JPG images: .JPG's are "raster" images.  Raster images can display photograph-quality images, but they don't scale very well.  Raster images are made of pixels, and when scaled, become distorted.  You cannot take advantage of a transparent background with a .JPG image.

This is an example of adding a .JPG logo to your project.  It cannot have a transparent background (note the orange region which comprises the image).

If we enlarge our view of that .JPG, you can see that it is "pixilated," or jagged.  This is because it is made of pixels, or tiny squares.

.SWF images: .SWF's are "vector" images.  Vector images usually don't display photographic quality images, but they scale perfectly.  Vector images are made of lines, causing no distortion when scaled.  .SWF files can also have transparent backgrounds.

This is an example of adding a .SWF logo to your project.  It features a transparent background.

If we enlarge our view of that .SWF file, you can see that it scales perfectly, without any jaggedness or pixilation.
