I'm not that motovated feldon ;p

I have two things to remark:

As you send a Location: header the Content-type: header doesn't matter as the browser makes a second request for the png file.

This second request takes some time so I suggest doing the "decision" directly on the server without the need of a second request. This only needs the Apache module mod_rewrite:Every non-existing gif file so gets redirected to a png file. I don't check if the png file exists but I think this doesn't matter ;)

Thanks Stefan,

it feels "faster".

I don't always replace all of the gif files, so I prefer my version.

Your version replaces all non existant gif files with png files - am I correct? Exactly the same does my code but without causing the second (unnecessary) request.

Both versions doing the _same_ thing - but in different ways.

If you have mod_rewrite on your Apache, I think the solution by Stefan is better.. else Zacherys

will this work on 3.7.0?

Don't know why it shouldn't?

I am trying to get this to work on my board which is 3.7.2 and I have followed the instructions correctly and created a image called newthread.png and then uploaded it to the correct directory and then deleted the newthread.gif but when I refresh the page I just get text saying "post new thread" and no image?
I am running vB 3.7.2, PHP 5 and I have asked my host if I have the necessary setting that this hack/mod requires and then said YES?

Anyone help me out please?
Thanks
Danny

You can easily rename a .png to a .gif and have the .png display normally in all major browsers.

No need for this hack.
