Drupal 7.x

Hello. Newbie here so please kindly redirect me if I am asking in the wrong place.

I am trying 7.x. I have a block generated by views that contains image field thumbnails.

is there a way to re-generate all thumbnails of image fields that are used in views?

having changed thumbnail size (admin/config/media/image-style) the old thumbnails remain the old size. Removing these thumbnail files doesn't help, as I don't know how to trigger the system to re-generate them.

When I defined new node type with node_type_save in foo.install, if I assign 'base' => 'node_content', Title field is visible, but if I assign 'base' => 'foobase', Title field is not visible.
Why?
Any comment or idea? What is the benefit of it? or.. is it a bug?

<?php
  $footype = array(
    'type' => 'footype',
    'name' => $t('Footype'),
    'base' => 'node_content',
  );
  $content_type = node_type_set_defaults($footype);
  node_type_save($content_type);
?>

has title field.

Hello,

I am in the process of installing Drupal 7 and am getting an error "Table variable already exists." when I try to connect to the MySQL database (due mostly to lack of imagination, I named the Drupal database 'drupal'). There are no tables in the mysql.drupal database and the username / password I am using allows login without error.

This install is on a fresh Ubuntu 9.10 server with PHP 5.2.10, and MySQL 5.1.37.

Hi Everyone,

I want to start an "Anonymous Proxy" Web site. Is there a module or any other technology that I can use within Drupal to create such as service? In Liferay, you can use "PortletBridge Portlet" which basically creates the proxy for you; but for obvious reasons I definitely prefer to do this with Drupal. So, is there any module for this functionality?

Thanks,
Dan

I have a fairly good understanding of PHP and how it interacts with databases as well as the MVC architecture, with that in mind what would be the best learning resource that i could obtain to help me learn drupal development. I have been considering picking up one of those lullabot videos because they seem fairly fast paced, but i have always been a sucker for books, so any opinions on that would be very much appreciated.

One thing I've been struggling with in Drupal 7 is inline images in my content. I tried creating a new image field but all that appears to do is stack all the images at the top of my content instead of allowing it to be placed where I want it inline. I'd really prefer a lightbox type arrangement where the user can load a full sized version over my content as needed, however there doesn't appear to be any updated Lightbox integration modules.
