How to specify rel=canonical

[ricercaviaggi]

Hello,
I renewed my license to download and fix duplicate title problem, as suggested. But I don't find how to specify the tag rel=canonical or avoid duplicate urls for the same photo. May you help me?
Thanks

The new SEO urls only have one url to a photo like so

http://www.reeftalk.com/gallery/Fish...n_Jawfish.html

a category is accessed like this

Fish Pics - ReefTalk Gallery

There are no multiple urls as no other variables are passed in a url anymore. options are done with cookies.

You can add that rel=canonical if you wish on the main image tag if you wish in the code but there should be no need.

Thanks. And if I don't use the seo option rewrite urls the url is still unique right?

The urls should be unique

Thanks, but in GWT I see all theese links and each one show the same page
/gallery/showphoto.php?photo=312&cat=views&limit=views
/gallery/showphoto.php?photo=312&date=1208455822
/gallery/showphoto.php?photo=312&date=1210060375
/gallery/showphoto.php?photo=312&date=1211216453
/gallery/showphoto.php?photo=312&date=1254517322
etc.

so I must add a rel=canonical instruction. How can I add this?

Moreover: trying to switch to seo mode, I see blank page: is missing some file?

[Chuck S]

did you rename HTACCESS to .htaccess

Thanks for info, now is fixed.

Now I have to disallow through robots.txt all showphoto.php , it's ok this instruction:

Content visible to verified customers only.

It's enough for SEO ?

you can do whatever you wish I would not disable bots from seeing showphoto but thats me
