Upon completing this lesson, several terminal objectives will be attainable:
Trainees will be able to explain what parts of a web page are usually graphics files.
Trainees will be able to determine the proper usage of gifs and jpegs, and what sort of image requires which format.
Trainees will be able to distinguish between two enlarged images, determining which image was "scaled" (distinguished by pixelation) and one which was "re-sampled".
Trainees will be able to state the largest recommended image area and average resolution recommended for web page images.
