Miscellaneous Hacks - NoMoreGifs

I had been working on a style for my now defunt site, while developing it, since IE7 was final and PNG's are just too cool to pass up anymore. I found it a pain to re-write all of the vBulletin templates to use the .png extension on the images. Not to mention this would make upgrading a pain in the butt.

I had Matthew make me this snipet of code. I told him I would release it and he said its fine.

So to you I now give you the ability to not have to use gif's but png's in your image folders.

You're webserver must support custom error documents via htaccess.

Installation,
Edit htaccess file to give a full/proper url to your new 404.php document
Put both the htaccess file and the 404.php file in the base of you images folder.

I only offer support when I have time. This modification is otherwise unsupported, but working.


For style developers, if you wish to use this, please give credit where credit is due , a link back to this mod would be great.

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:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.*)\.gif$ $1.png [NC,L]

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

Can you please explain a bit more?

Do I have to add those lines in my ".htaccess" file? Is that all?

In my root folder I can't see any mod_rewrite. I'm sorry but I know nothing about this.

Thank you in advance.
