htaccess mod_rewrite

I have a small script setup to insert watermarks on images in a directory. Instead of viewing images/boy.jpg, my .htaccess will automatically call images/watermark.php?img=boy.jpg, and the watermark is displayed. This is working correctly.

However, I want to NOT rewrite watermark.php OR any images with "_thumb" in the filename. Here's what I've got:

RewriteRule ^(watermark|watermark/watermark)\.php$|^.+\.(css|js)$ - [L] 
RewriteRule ^(thumb|thumb/thumb)$|^.+\.(jpg|jpeg)$ - [L] 
RewriteRule ^(.+) watermark.php?img=$1 [L]

Code (markup):

Something with the syntax in the second line is not correct. The watermark is still being displayed on the images with "_thumb" in the filename.

Any assistance please????

 

i cant find any error myself but i am not pro .
Someone pro should help you soon.

Maybe try to
make a rewriting rule for that too: _thumb

 

The rewrite rule for _thumb is the second line of code I posted above, but thats what is not working.

 

How about this?

RewriteRule ^(watermark|watermark/watermark)\.php$|^.+\.(css|js)$ - [L]
RewriteCond %{REQUEST_FILENAME} !_thumb
RewriteRule ^(.+) watermark.php?img=$1 [L]

 

That did it. I really appreciate it! +rep
