Robots.txt and joomla

[seoanalytics]

Hello,

I use joomla for my website and automatically all those files are blocked is that good or bad, so I remove anything and if so why ?

User-agent: *
Disallow: /administrator/
Disallow: /cache/
Disallow: /components/
Disallow: /images/
Disallow: /includes/
Disallow: /installation/
Disallow: /language/
Disallow: /libraries/
Disallow: /media/
Disallow: /modules/
Disallow: /plugins/
Disallow: /templates/
Disallow: /tmp/
Disallow: /xmlrpc/

I also added to my robots.txt files my email address ( is that useful, I am afraid google passes PR to the email address  )
and a javascript: void (0) because I have tabs on my webpage  ( is that useful )
as well as a .pdf ( is it also useful )

any comments ? does anything need to be changed or is it ok ?

Thank you,

It let your image be found for Google or other Search Engines. If not remove that line, none images will be show on serps. I don't know why Joomla gives robots.txt as this, but you need to change it.

Is removing the / image /  better in terms of SEO bercause of the lat tags etc... or just people to find my website via the images ?

You must remove the line

Disallow: /images/

and let you images to be found.

I hope this can help you
