When we're at our computers, most of us don't have the luxury of a 21-inch monitor. I'm opposed to anything that reduces the effective screen size of a monitor, giving us a smaller window to peek through. Images displayed on pages that are made with frames must be smaller than the window the frame provides, or visitors will have to scroll around to see all of its parts and then try to visualize what the whole image looks like when it's all put together. Most people don't know that they can do this. But when you're at a site that's made with frames, you have to click on a frame and load the images in that frame, and then click somewhere else and load the images in that part of the screen.
Frames often slow down page loading.
For some reason, sites made with frames tend to cause systems to freeze up or crash far more often than those without frames. The only people that seem to like frames are people who create Web pages for others, and especially the kind of Web page designers that like to show off what they can do. I wish frames had never been developed. The only frames I would ever use are made of steel. Just pure, clicking satisfaction.
