How to redirect an url in .htaccess when "redirect 301" doesnt work

[Status]

I have an odd page url, generated by a link from an external website, it has:

%5Cu0026size=27.4KB%5Cu0026p=dell%20printers%20uk%5Cu0026oid=333302b6be58eaa914fbc7de45b23926%5Cu0026ni=21%5Cu0026no=24%5Cu0026tab=organic%5Cu0026sigi=11p3eqh65%5Cu0026tt=Dell%205210n%20A4%20Mono%20Laser%20Printer%20from%20Printer%20Experts%5Cu0026u=fb

,after a .jpg image url, and I can't get it redirect using the redirect 301 in .htaccess to the properly image url as I use to do with the rest of not found urls

eg: /15985.jpg%5Cu0026size=27.4KB%5Cu0026p=dell%20printers%20uk%5Cu0026oid=333302b6be58eaa914fbc7de45b23926%5Cu0026ni=21%5Cu0026no=24%5Cu0026tab=organic%5Cu0026sigi=11p3eqh65%5Cu0026tt=Dell%205210n%20A4%20Mono%20Laser%20Printer%20from%20Printer%20Experts%5Cu0026u=fb

to just: /15985.jpg

There's a few different methods of doing a redirect or a rewrite which might work. What code are you trying to use for the 301?

Have you tried:

redirect 301 15985.jpg(.*) 15985.jpg

This should capture every string that starts with the image name.

Hope that helps.

Sorry, I couldn't get it redirected with this, this is a really naughty url coming from an external website,
but thanks for suggestion

[WilliamKammer]

Sorry, I should have clarified. The redirect needs the full path of the image. The actual redirect would be something Ike:

Redirect 301 /images/15985.jpg(.*)   /images/15985.jog

depending on where the image actually lives.
