Using PNGs with Transparent Backgrounds

[td.im]

I created some circle/buttons that float around the html page on a dreamweaver
timeline.
On my mac, safari browser they work fine. They fly in and out as circles with
a transparent background since photoshop creates images in squares or
rectangles. On PC explorer broswers the transparency turns to a white
background. This also happens when I create a photoshop png that is a
transparent background with just type. The image of the word comes in on a
white block. Is there something I can do to these images to make it work
transparent?

There is no easy solution. Thats because Microsoft sucks. You have two
options...

Block IE users and tell them to switch to Firefox (easiest)

or

Go here... [url]http://www.mongus.net/pngInfo/[/url] and use that. (preferable)

It depends on the kind of transparency you use. An PNG that uses single
color transparency like a GIF will work fine in IE. A PNG that uses alpha
channel transparency (translucency is a better word in this case) need to
have IE use an add-in to process the image.

There are plenty of hits on Google for "IE PNG alpha transparency."

I use png's all the time with no problems.

In fact, kilobytes are saved all round with png's winning over your average
gif with less file size and sharper images.

As stated, as long as you don't meddle with the transparency, it works great.

Try saving a two colour image to a gif and a png and see what wins.

After 15 or 20 colours, its time for your jpeg.

Gifs are doomed.
