PNG graphics transparency
Hello world,
I want to use a PNG graphic with transparent regions on my website. However, Internet Explorer (latest version from WinXP SP2) displays transparent regions kind of bluish instead of using the background color. As I am quite new to HTML, do I have to set special options for PNG to work? Jens Jens Lenge |

> I want to use a PNG graphic with transparent regions on my website. Unfortunately, the problem you are encountering is because Internet Explorer does not support alpha transparency (transparency in 24-bit PNG files). You have one of two options here, you can either use a GIF or PNG with a single transparent colour (256 colours overall), or you can use some clever server-side stuff to get Internet Explorer to work with 24-bit transparent PNGs. As you are new to HTML, I would suggest that you do the former of the two options, until you are ready to delve into server-side stuff. -- Dylan Parry http://webpageworkshop.co.uk - FREE Web tutorials and references |

Re: PNG graphics transparency
I will check out the different approaches.
Thanks for all the advice! (It's good to know one is not alone in the net...) Jens |

Mozilla and Konqeror can display a full-colour PNG with transparency. Window$ (I tested IE5 and 6) wants a bloody indexed pallete. Unless you ignore Window$ users, you are forced to reduce the quality of your graphics. ....don't get me started on the way IE renders tables. It drove me nuts yesterday. -- Roy Schestowitz http://schestowitz.com |

Clever client-side stuff that's dynamically created with clever server-side stuff. |

Thank you. That is what I mean. Just because some server-side stuff creates the code doesn't make it a server-side workaround. It is purely client side.
