Hmm, that would be unneccessary. Unless you plan to alter the picture,
just do a header & a readfile('test. png'); Tremendously saves memory usage.

I agree with the second poster - I don't think you can change the types
with .htaccess. You could try using mod_rewrite to direct everything from
, say, "/image-12345.png" to "image.php?id=1 2345". I'm not great with
regular expressions but I'm sure someone else can help you out with that.

Thanks all for the responses. It's much appreciated.

Here's what I ended up using:

AddType application/x-httpd-php .png
RewriteEngine On
RewriteRule .png /phpsigs/create-sig.php

basically just redirects all .PNG requests to a single PHP script, I
can then grab the file name, etc and personalize the image being
returned.

With thankful regards,

BK

Hmm, either parse png's for code, or rewrite the url's. Doing both is just
silly, so I'd lose the AddType...

Thanks both.

I did lose the AddType in the end, but didn't know about [QSA,L] -
what does that do? seems to work ok without it, but would be good to
know what it's for.

Hmm, you'd think when doing rewrites one would consult the manual.

mod_rewrite - Apache HTTP Server

http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html#rewriterule

See 'Flags'.

AddType defines the mime type of file extensions. mime types are how
the server knows the difference between images, plain text and other
files. This information also carries over to the browser so it is
able to display the information correctly.

I believe the original problem was that AddType image/png .png
occurred before you told Apache to parse it as php. I gather that it
defaulted to the first one defined.

In any case, defining the content type from within PHP is the best
option in this case. It prevents real pngs from being parsed as php.
