need help with rewritting rules

hello i have a question about rewriting rule
i have 4 thumbnails galery that onmouseover display data and picture with ajax it's associated with limits: 5 thumbnails are displayed starting display from limits given trough url, and an arrow able the visitor to see five more.

what i would like is to have a link to each thumb going to the same page than the script info display but displaying picture and infos through a google/ and robots friendly environnment that means no ajax but i would display the <img src="myimage.jpg"> with myimage.jpg coming fom the location url

currenly i use the following rewriting rule:

RewriteRule ^print/([a-z]{2})/([0-9]+)/([0-9]+)/([0-9]+)/([0-9]+)/?$ /print.php?lang=$1&limite1=$2&limite2=$3&limite3=$4&limite4=$5
RewriteRule ^print/([^/]*) /print.php?lang=$1&limite1=0&limite2=0&limite3=0&limite4=0
but limits works only for one section (board) at the moment

so i think it will evolve to something longer

and would give a location something like http://localhost/print/en/1/0/0/0/0/myimage.jpg

what do u thing?
would my rewriting rule be like this?

RewriteRule ^print/([a-z]{2})/([0-9]+)/([0-9]+)/([0-9]+)/([0-9]+)/([a-z])/?$ /print.php?lang=$1&limite1=$2&limite2=$3&limite3=$4&limite4=$5&limite5=$6&image=$7

RewriteRule ^print/([^/]*) /print.php?lang=$1&limite1=0&limite2=0&limite3=0&limite4=0

thanks for your precious help

Each number after a $ in the replacement refers back to a capturing group in the pattern ie it's a backreference. You can't have more backreferences than you have capturing groups.

Your rule:
RewriteRule ^print/([a-z]{2})/([0-9]+)/([0-9]+)/([0-9]+)/([0-9]+)/([a-z])/?$ /print.php?lang=$1&limite1=$2&limite2=$3&limite3=$4&limite4=$5&limite5=$6&image=$7
has 6 capturing groups, but has a backreference to $7 so I believe it would fail with an error.

Could you please give some clarity as to which source URLs you want redirected to which target URLs. eg

"I want to redirect:
print/fr/
to
print.php?lang=fr&limite1=0&limite2=0&limite3=0&limite4=0

and
print/fr/5/
to
print.php?lang=fr&limite1=5&limite2=0&limite3=0&limite4=0
"

i would like
to redirect

print/fr/1/0/0/0/0/folder/image.jpg

to print.php?lang=fr&galerie=1&limite1=0&limite2=0&limite3=0&limite4=0&show=folder/image.jpg

would it be wise?
maybe i don't need to use a folder/ and use directly the image but in a first time i would like to know how you can use it and redirect it

i would like to display the image using $show,
thanks
