Case Based Critical ThinkingCase 1As the designer for an online catalog, Rob is extremely familiar with the various ways he can add photos and other graphics to websites. He just hired Beth to be his assistant, and while she is very good with the planning process, she lacks some skills when it comes to actually putting the pieces of the catalog together using Dreamweaver. Always patient, Rob has decided to take Beth under his wing and teach her what he knows. Beth wasn't very clear on the various types of graphic file formats used when creating the catalog. Which of the following formats does Rob tell her they will use for the catalog photos, and why?
A. PNG, because it is supported by the most current browsers B. TIFF, because although it is limited in the number of colors it can represent, it shows transparent areas well C. JPEG, because it can display so many colors and will give an accurate picture of the products in the catalog D. GIF, because it is the fastest to upload
