Image prefix (url rewrite)

问题

I'm use this tutorials to add watermark on my images: http://www.reviewsforjoomla.com/forum/index.php?topic=15067.0

All JPG are correctly marked up with this htaccess rule:

RewriteEngine on
RewriteRule ^([^tn].*\.(jpg))$ watermark.php?image=$1&watermark=watermark.png [NC]

Now, i need to apply different watermarks based on file prefix, like:

AA-myimage.jpg (apply aa-watermark.png to all files with AA- prefix)

BB-myimage.jpg (apply bb-watermark.png to all images with BB- prefix)

There is a way to add this on htaccess?

Thanks all!

Try this rule:

RewriteRule ^([a-z]{2})-(.+?\.jpg)$ watermark.php?image=$1-$2&watermark=$1-watermark.png [NC,L]
