IMAGES ON THE WEB

  Images displayed on the web should be converted to one of the formats supported by most browsers: GIR. JPEG, of PNG, GIF and JPEG are the popular standards, and every response to some patent issues with the GIF format. IT’s superior to GIF in almost every respect, but old prowess doesn’t support it. Many other image formats are supported by some browsers and not others. You should avoid them.

Let’s assume that you already have an image you want to put on your web page. How do you get it into GIF or JPEG format so it can be viewed on your page? More image edit – king programs, such as Adobe Photoshop (http://www.adobe;com/), paint shop pro (http://www.jasc. Com/),and CorelDraw (http://www.corelcom/), will convert images to most of the popular formats. You might have to look under the option for save as or export of find the conversion option. There are also freeware and shareware programs for most platforms that do nothing but convert between image formats. Many shareware and demo versions of image editing programs are available at http;///ww.download. com /(search poor “image editors” using the software platform of your choice).

TIP

If you’re a windows user, you can download irafanview, which allows you to view images, and convert them to various formats, at http://www.infanview. Com/. It also provides a number of other image manipulation features that are useful for working with images for the web. Best of all, it’s free for non-commercial use.

To save files in GIF format, look for an option called CompuServe GIF,gif87, GIF89a, or just plain GIF. Any of them will work. If you’re saving your files as JPEG, usually the option will simply be 

JPEG.

Remember how your HTML files have to have an. Html or. Html extension to work properly? Image files have extensions too. For GIF files, the extension is. Gif. For JPEG files, the extensions are. Jpg and .jpeg.

NOTE

Some image editors will try to save files with extensions in all caps (.GIF ro. JPEG). Although they’re the correct extensions. Image names are case sensitive, sol. GIF isn’t the same extension as. Gif. The case of the extension might not be important when you’re testing on your local system, but it can be when you move you files to the servder, so,use lowercase if you can.
