Drupal 7.x

i got when when create new user from admin account:

# Warning: mail() [function.mail]: Failed to connect to mailserver at "mail-out.cytanet.com.cy" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in DefaultMailSystem->mail() (line 77 of C:\xampp\htdocs\drupal-7.x-dev\modules\system\system.mail.inc).
# Unable to send e-mail. Contact the site administrator if the problem persists.

i did not get email, although i get email when do account from normal web page as a visitor, well?

Can anybody help me? Im using D7, I created a nodetype gallery and and setup unlimited images. Now what I want to do is create a "views" that will display the 6 most recent photos. My problem is that the images are not nodes, and I cant find way on how to limit the photos and at the same time display the 6 recent ones.

Any help is highly appreciated =)

I found problems to see where is the php function to encode data in table 'variable'

INSERT INTO `dp_variable` (`name`, `value`) VALUES
('admin_theme', 0x733a353a22736576656e223b),
('clean_url', 0x733a313a2230223b),
('comment_page', 0x693a303b),
('configurable_timezones', 0x693a313b),

In which file is it and where exactly ?

We are going to redo our website. I am doing the products research and decide which one is the best for our org. I would greatly appreciate your advices/opinions if you could help me get some more understanding about drupal's capabilities.

Here are our requirements:
1. membership management. we are a membership based org, and need a integrated DB to manage/track our members info (mostly done by admin)
2. registered user management. Different from membership management. users can sign up on our website and get some benefits: such as subscribe newsletters and get emails etc.
3. permissions control based on the users roles. for example, org members can download files for a certain event, but regular registerd users cannot
4. e-newsletter: edit and distribute emails based on the subscription mailing list. and also need to achive these newsletters based on the categories and date/issues
5. e-calendar: events/calls announcement. admins able to add descriptions and upload files, send email reminders. registered event/calls users be able to download files/materials. After the event/call expires, they should be archived along with the descriptions and materials/files based on the categories and dates

I seem to have been going around in circles. On my Drupal 6 site I can link images through CCK and the image link module to other nodes (not the image none) on my site.

Does anyone have any idea how I could do this in Drupal 7? The only links available in manage displays are none, file (the image file) and content (the image node).

Thanks in advance for any suggestions.

Hello!

I've read this post: http://drupal.org/node/197145 , but I didn't find it particularly helpful. I am new to drupal and the complex vocabulary isn't helpful. I find that the fact that I'm using version 7 isn't helpful either, as there were many changes with the upgrade.

The issue:
I have a main menu:
Home > Leisure activities > Crafts
Home > Leisure activities > Cooking
...etc

I made Crafts and Cooking "basic pages" (D7 vocab).
