Recently web have become more multimedia oriented than in its early days. While in some domains the new technologies work and prove successful. On the other hand, flash just makes browsing more time consuming. Here I point out the drawbacks of using Flash as well as give some pointers on how to better use it. 最近，所有的网络似乎变成了以多媒体为导向了。在一些域名中，新技术已经得到了成功的运用。换句话说，flash的使用频率越来越高。但是在这里，我要向大家指出一些使用flash的弊端，并告诉大家，应该如何使用flash。
Flash is trendiest technology currently used in web design. Nearly everyone ranging from beginners to experienced web designers learn how to create and implement Flash in their websites. There is a chance that when the web will become more of a WebTV and multimedia show, Flash will replace almost completely the HyperText Markup Language (HTML). Flash has been the "releaser of energy" for all the trendy web designers on the Internet because it allowes them to express more of what they wanted to say. Soon, Flash has literally taken over thousands of websites. While Flash can be successfully used in web sites with profiles in music, multimedia, online games, interactive activities etc, on most sites Flash is used for the sake of using it and raises serious issues for users. Top notch professional developers & designers avoid flash though it adds some extra bounce. Why? On slow Internet connections such as dial up the flash page loads over a long period or doesn't. Flash is not bandwidth friendly and many designers do not create Flash files bearing this issue in mind. Users on slow connections have to wait a fair bit of time before the web page with Flash loads. Again to see flash pages you need Flash Player - Plugin to be installed in your system. There are still many users who do not have the Flash player installed and they can't se the pages. It is not fair to exclude these users from using a website for the sake of design. Design and all the technologies employed in creating it, should aid users in finding the information they seek not slow them down in doing so.
flash是当今网页设计中的流行元素。几乎所有的网页设计新手和老手都试图掌握如何在他们的网站中执行flash，这样会使得网站更多地像“网络电视”和“多媒体秀”。flash几乎要代替整个超文本链接语言了（HTML），变得有点像设计师们“展现自我能量”的工具了。几乎所有的网络设计师都愿意通过flash来表达他们希望表达的内容。霎时间，flash开始频繁现身于各大网站中。Flash可以在网站中成功地运用音乐、多媒体、在线游戏和互动等项目。大多数网站flash都会利用上述这点来获取更多的读者。最顶尖的开发者和设计师拒绝在特殊的情况中使用flash，为什么呢？如果网络连接很慢，如拨号连接，那么很多设计师就不愿意创建flash，因为这会影响下载时间。网速较慢的用户必须要等待网页加载flash的时间。并且，如果你需要在网页中播放flash，你还必须在页面中安装插件。不要忘了，这里还有很多人没有安装flash播放插件，因此，不能浏览网页。那么把这些浏览用户排出在外，我想并不是明智之举。设计网页时，或在网页中运行特定的技术时，不应该牺牲用户查找信息时所花费的时间。
Reaction of audience to Flash
访问者对于flash的反应
There are mixed opinions regarding Flash web sites. When average people are presented a Flash website they are compelled by the visuals, motion and sound. They appreciate its "good looks" and again we, the designers cannot deny that Flash design looks good. When average people look for information through search engines, links from other sites or their own bookmarks, Flash annoys them. It makes them wait an extra 1, 2 or 5 minutes before they get to the information they seek and they're likely to move to another site where that doesn't happen. If in the first instance people like and appreciate the visual appeal of Flash, in the second instance they would rather not encounter it. This is a very important point that Flash designers should take account of.
对待flash网站，这里有几种不同的意见。当普通人访问flash站点时，他们都会被一种视觉、动画、声音所冲击。他们认为flash站点非常好看，同时，我们这些设计师们也并不否认，flash站点确实视觉效果很不错。当普通人通过搜索引擎搜索信息时，来自于其他站点的链接或书签、flash都会对他们造成影响。他们可能必须多等上1秒、2秒或5秒钟才能获取他们所需要的信息，这时，他们可能会转而访问其他网站。可能有些人在第一次访问flash站点时会感到效果不错，但是第二次再访问时，可能就不会这么认为了。所以设计师们必须时刻准备为自己设计的flash网站付出代价。
Then Why Do People Ask For Flash Websites?
为什么人们希望创建Flash网站？
Some people want Flash websites because they've seen their competitors, friends or family using Flash in their websites and want to have good looking sites like them too. However, they overlook the fact that when searching for information on the web they would probably skip a Flash website. Flash is a trend. If the neighbor’s got it I've got to have it too. Flash is good for personal portfolio, group site, presentation. Search engines skip flash sites while their bots visit www.
一些人非常喜欢flash网站，因为他们看到自己的竞争对手、朋友和家人都在网站中使用flash，希望是自己的网站也和他们的网站看起来一样美观。然而，他们忽略了一个事实，当在搜索网站中搜索信息时，这些flash网站可能会被跳过。Flash是一种趋势。如果我周围的人使用它，那么我也使用它。Flash对于描述个人资料、群组站点和在线展示非常有效。当搜索引擎机器人读到www时，他们会跳过flash站点。
Flash and Accessibility issues
Flash和可访问性议题
Unfortunately, alternate browsers have not reached the point where they can properly read Flash files. Flash files often do not contain just images in motion but also text. Screen readers, voice browsers and other alternate browsers cannot retrieve such information. Flash is often used because it's visually compelling. Visually disabled users are unable to enjoy or appreciate the visuals and the animation like average people do. Special care must be taken when designing with Flash and considering accessibility issues.
不幸的是，并不是所有的浏览器都可以读取flash文件。Flash文件通常在动画中包含图片和文本内容。某些显示器、声音浏览器和其他的浏览器可能并不能获取这些信息。Flash经常被使用的最大一个原因就是：它具有极强的渲染力，十分引人注目。但是对于盲人用户来说，他们就不能够像常人那样自由地享受和欣赏视觉动画。所以，你必须要好好考虑该如何设计flash站点以及可访问性的问题。
Pointers for Flash designers
对flash设计师的忠告
Do not create website entirely in Flash. You will shut out a big percentage of your users. If you must, then a HTML version of the site is preferred as well. Again if you are using flash sites for your business then probably you are thrown away by all the major search engines.
千万不要把整个网站创建成为flash网站，那么你会失去大部分用户。如果你必须这样，那么你必须得把网页设计为HTML形式的；与此同时，如果你是为了商务业务而开发flash站点，那么，所有的搜索引擎都会拒绝你。
