It could, but it is not relative to the php-file. So the relative url would be something like:
<img id=”about” src=”/wp-content/themes/Your-Theme/images/about.jpg” alt=”about”>/

Try using the get_template_directory_uri() function.

<img id="about" src="<?php echo get_template_directory_uri(); ?>/images/about.jpg" alt="about" />

Ok, thats strange:) Seems like something is corrupted. You can try troubleshooting with one of the following:

1. Upload a new wp-login.php file (Make sure you get the wp-login.php-file from the correct version.
2. Log in from wp-login.php (http://www.yourdomain.com/wp-login.php)
3. Disable plugins (Rename the Plugins folder to something else, like pluginsX)
4. Try resetting your password with the reset password link

There is also some more tricks here: http://codex.wordpress.org/Login_Trouble

Look under Settings->Reading here you can set you front page for your blog. Please also provide some more information like what theme are you using, an url to your website etc. (http://codex.wordpress.org/Forum_Welcome)

You have to insert a new row in the wp_users/wp_usersmeta table in the database. If you have access to phpMyAdmin(or any other application to handle MySQL) follow these steps:

Select the wp_users table, and click the Insert-tab

1. user_login – this is the username you want to use
2. user_pass – this is the password you want to use (be sure to select MD5 from the Function menu)
3. user_nicename – put whatever you would like to refer to yourself as (not your username)
4. user_email – this is the email account associated with this user
5. user_url – the url to your website
6. user_registered – when was this user registered – just select a date with the date selector
7. user_activation_key – you can leave this blank
8. user_status – leave this set to 0
9. display_name – same as user_nicename

Click Go/Save/Run 🙂

If everything is OK, continue to the wp_usermeta table. Here you would need to insert two rows, first:

1. umeta_id – leave this blank(it is automatically generated)
2. user_id – this is the id of the user you created in the previous steps
3. meta_key – for this step insert wp_capabilities
4. meta_value – insert exactly this – a:1:{s:13:”administrator”;b:1;}

Second insert:

1. umeta_id – leave this blank
2. user_id – this is the id of the user you created
3. meta_key – for this step insert wp_user_level
4. meta_value – insert 10

Hope this helps 🙂

Do a Search and Replace directly in the database as suppose to doing it on the .sql file in a text-editor as this can cause som trouble.
Here are the wordpress guide from the codex:
http://codex.wordpress.org/Moving_WordPress#When_Your_Domain_Name_or_URLs_Change

, and a good serch and replace script:

Remember to back up you database before you start 🙂

This is probably in your themes comments.php-file.
