Because the exercize asked that I save files as. jpg and .gif, I did not practice with .png as much. The lecture notes state that while Portable Network Graphics (pgn) are "a very useful alternative" to the Graphic Interchange Format (gif) and Joint Photographic Experts Group (jpg) formats, PNG has not yet become very popular on the WWW (City University 2009). In my experience looking at the image sources on web pages, this assertion certainly seemed to be the case. I first wanted to attach an image that my friend Emily had displayed on the web, but she had displayed the image on Livejournal as part of a slide show, and I could not separate one of the images from the others. When I tried to find the link to the image by viewing the website as an HTML document, rather than an application on Flash, I noticed that she had uploaded the images from her computer using gif. I gave up trying to use her images, and instead used an image from Flickr that was posted by the USA Today. The image that I ended up using has been saved under jpg format.
When you look at the two images on my website, one is a lot grainier than the other. The difference is not due to the formats they have been saved in; they are both .jpg files. The difference is because the first one—the grainy one—is a snapshot that I took, and the second one is a professional photograph put out by USA Today. Here's a link to my website
