Graphics for the web: The Most Common Formats

Written by Richard Lowe

One ofrepparttar early problems onrepparttar 134635 net was how to display graphics. The first browsers only displayed textual information -repparttar 134636 modern browser with it's images, multimedia and plugin's did not exist. Everything was text based.

Now there are hundreds of image formats, although only a handful are actually appropriate forrepparttar 134637 internet. And to make things even more confusing, there are additional ways to display pictures including Java, ActiveX, Dynamic HTML and so on (although these tend to just display variations onrepparttar 134638 standard web graphics formats).

And if that wasn't bad enough, email and newsgroups never evolved a real, built-in standard for images. These two formats are text based and have remained so in spite ofrepparttar 134639 changes in browsers and technology. Special encoding technology has been created to allow attachments to be sent with messages. Most ofrepparttar 134640 modern email clients detect this and performrepparttar 134641 conversion automatically.

Forrepparttar 134642 web,repparttar 134643 dominant formats are GIF and JPEG. BMP (bit mask images) are occasionally used, andrepparttar 134644 up-and-coming PNG format seems poised to threaten GIF in a few years. The GIF format is perhapsrepparttar 134645 oldest and most powerful ofrepparttar 134646 formats (except forrepparttar 134647 limitation of 256 colors), since it supports animation, interlacing and transparency. The other dominant format, JPG, tends to create smaller, albeit fuzzier images.

The three major web formats for graphics are described briefly below.

GIF (Graphics Interchange Format) - This is probablyrepparttar 134648 most widely used format onrepparttar 134649 internet. It was created by CompuServe in 1987 to display images on their service. Some ofrepparttar 134650 great features of this graphics format include:

- Excellent compression - images created inrepparttar 134651 GIF format can be optimized to very small sizes.

- Interlacing - Allows images to "fade" in slowly. This is very useful for large images.

- Transparency - The ability to make a color be transparent, allowingrepparttar 134652 background ofrepparttar 134653 web page to show through.

Web Site Design: Pulling Them In Deeper

Written by Richard Lowe

Good web sites take full advantage ofrepparttar features of HTML (andrepparttar 134634 various client- and server-side scripting languages), which allow pages to be linked together at will. You need to remember that your web site is not a book, a poster or a brochure - it is a web site. By taking full advantage of this fact, you can increaserepparttar 134635 time people spend reading your pages, looking at your images, listening to your sounds, and possibly purchasing your products.

Some people actually debaterepparttar 134636 need to keep visitors on your web site for any length of time. I have heardrepparttar 134637 argument that it doesn't matter how long they stay - you really just want them to purchase something and then leave. Unless you have created a very specific, extremely targeted, one or two page web site, then that thinking is hogwash.

Look, you've gone to a lot of work to create a wonderful web site. You have tons of great content for people to look at. Perhaps you have some awesome products to sell or a message to get across. The longer that people stay,repparttar 134638 more likely they are to see your message or purchase your products. You can almost translaterepparttar 134639 length of their stay directly to interest in what you've got to say.

So how do you get people to stay on your site for any length of time? Well, you include great content which is linked together in such a way as to pull people deeper into your site. Give them plenty of ways to explore what you've got.

Don't design your site as one huge long page. Remember that you are creating a web site, so split those long pages up into short articles and link them together logically. Your visitors like seeing one or two screen's worth of information at a time ... any more and they will just not scroll down to see it.

Link your pages together in all manner of ways. Give your visitors plenty of ways to explorerepparttar 134640 fullness of your site. You should have a normal navigation method (let's say a standard menu downrepparttar 134641 left side) which is very organized. In addition, you should strategically place links to random but related content all over your site. And remember, all of these links should be internal to your own site, not external links. You want people maneuvering around your pages, not leaving to someone else's site.
