If you've used Photoshop, you've undoubtedly used Layer Effects; it's used for a variety of purposes including graphics design, thumbnails, and a variety of other visuals.
You may not find the layer effect option in gimp, but it doesn't mean gimp can't create such effects, and producing those effects is a lot easier than you think.
There are effects scattered throughout Gimp that will produce the same effect as Photoshop's layer effects.
We will not be covering all of the effects of the layer, but all the major ones.
