Be careful with the image sizes
Each image is embedded into the Flash swf files as JPEG files.
This means that the Flash file could easily grow to a big
size. Also put yourself in your web site visitors place, you
wouldn't like to download a big effect file each time you
enter a web site, right? This also applies to fonts, effects
with embedded fonts are generally larger than effects that
use the normal system fonts. However, this may give you only
an extra size of 10-30 kbytes, depending on the font. The
font size will not affect the SWF file size.
Maximum number of objects
There is a limitation in the Flash player that puts a limit
on the number of objects you can have in a flash file to maximum
200. An object could be an image in imagefader or a text line
in verticalscroller. Look carefully at each applet's help
file to see its limits. For instance, putting 200 images in
imagefader would cause it to crash.
Don't put too much on a single web page
Some web designers may act like boys with a new toy when
getting access to a service like this, and they will put effects
all over their page. However, we do not recommend putting
more than 2-3 Flash or Java effects on a single web page.
Some effects are processor intensive and putting too many
on one page will cause a "competing effect", that
is that the effects will compete for system resources and
everything will run slowly. Note that a web site visitor may
have a slow computer, and the computer you design your site
on may be very fast. But if you stick to the rule of putting
few effects on a single page, you'll be fine. Also, a page
with too many effects may also annoy your visitors.
A large effect area may slow down the effect
Be careful when you specify the applet window size in pixels.
The bigger window, the more the computer displaying it will
have to work. If you need to have a large window and you note
that you are stressing the limits, then make sure you don't
put more flash effects on that specific page. Also make sure
someone with a slower computer may enjoy the effect. You could
simulate a slower computer by putting two or three windows
next to each other with the web page you want to test.
