Please help me with follow rewrite rule

Server NGINX
1

here is the structure:
/images/thumbnails/
/watermark

i use follow rewrite rule to add a watermark on my pictures.

rewrite ^/images/(.*).jpg /wm/wm.php?$request_filename;

i found it will rewrite with images/.jpg and image/thumbnails/.jpg,
but actually i only wanna rewrite images/*.jpg, not subdirectories. then
i change it to:

rewrite ^/images/(.[^/]).jpg /watermark/image.php?$request_filename;

my opinion is fit all character except “/” so that i can remove all
subdirectories from the rewrite rule.

but unfortunately, it doesn’t work well, /images/*.jpg can’t be rewrited
too.

is there anybody help me with this case?

thanks a lot.

And try pcre manpages, in particular ‘man pcrepattern’. Using
pcretest to test things is good idea, too.

You regex is incorrect. Furthermore since you’re not doing any
capturing or using alternative patterns drop the group.

rewrite ^/images/[^/]*.jpg /watermark/image.php?$request_filename;

It matches any file only under the images directory ending in .jpg.

hello Almeida,
if there is a structure like:
/images
/2010
/thumb
/2009
/thumb
…
if i want to match all jpg files in directory images, except jpg files
in every thumb directories, what should use?
i try

rewrite ^/images/[^/thumb/]*.jpg
/watermark/image.php?$request_filename;

but it can’t work well…
thanks a lot.
