Q&A

Q1:Can I mix the kinds of images I use on a Web page—some JPEGs, some GIFs, a PNG—or will that cause everything to crash?
A1: There is no reason not to mix image types. Choose the type depending on the content of the image. Realistic photos look best as JPEG or PNG files. Graphics with limited color are most efficiently stored as GIFs.
Q2:What's the trick for using a picture as a page background?
A2: Keep it small and apply the picture as a tiled background. If you keep the edges blurry, they blend smoothly, avoiding that floor tile look. Save your file as either a GIF or JPEG with the name background. Your Web page creator program should be able to insert it automatically, but if not, use the HTML tag <body background = "background.gif">. (Or .jpg, if appropriate.)

Another effect that uses the whole photo once is to make the image nearly transparent so it looks really toned down. Use it as a non-tiled background (watermark).

Q3:If I want to put my pictures on the Web, but only for my friends to see, can I protect them?
A3: There are lots of ways to do this. The easiest is to put them on a "hidden" page. This is a second page on your site, not linked to the first. Instead it has a separate address, such as home.myservice.net/mypage/hidden.htm. Give your friends the direct URL to this page. No one who doesn't know it's there will be able to reach it. However, "security through obscurity" is never a recommended policy for truly sensitive information or images. If you want to be more secure, you can learn enough JavaScript to password-protect the site. Look for Pure JavaScript by Sams. It's a good way to learn JavaScript.
