I do not get involved with this aspect of web page publication, but it would be a dereliction of my duties not to bring this kind of thing to your attention occasionally so that you at least have the opportunity to make up your own mind based on facts, not just opinion. So in this article I will discuss some of the pros and cons of editing flash based software and its effects on your web pages.
Flash’s Action script opens up a vast field of possibilities. Programmers and designers have used Flash to create interactive features ranging from very lively feedback forms to attractive Flash-based games. This whole new level of interactivity will always leave visitors coming back for more.
With Flash, you do not have to worry about cross-browser compatibility. No more woes over how a certain css code displays differently on Internet Explorer, Firefox and Opera. When you position your site elements in Flash, they will always appear as they are as long as the user has Flash Player installed.
There’s better expression through animation
In Flash, one can make use of its animating features to convey a message in a much more efficient and effective way. Flash is a lightweight option for animation because it is vector based (and hence smaller file sizes) as opposed to real “movie files” that are raster based and hence much larger in size.
The not so good:
The Flash player
People have to download the Flash player in advance before they can view Flash movies, so by using Flash your visitor range will decrease considerably because not everyone will be willing to download the Flash player just to view your site. You’ll also have to put in additional work in redirecting the user to the Flash download page if he or she doesn’t have the player installed.
Its loading time
Users have to wait longer than usual to load Flash content compared to regular text and images, and some visitors might just lose their patience and click the Back button. The longer your Flash takes to load, the more you risk losing visitors.
If your content was presented in Flash, most search engines wouldn’t be able to index your content. Hence, you will not be able to rank well in search engines and there will be less traffic heading to your site.
If you really so want to install a webpage or pages with Flash, make sure you do so with best intent… that you cannot work without the need for it. If you honestly cannot get away with not using it, so be it but as you have rad above I will not recommend it and would advise that unless you’re totally comfortable with it, then outsource to an expert who can write the scripts for you advocate it for the way I work or for those I coach.
