Images in blog should work more like Drupal where the primary image can be resized for different display modes

I would like to see content have an optional primary image that can be themed for the different build modes.

I was surprised to discover that using the rich-text image insert approach defeats the typical Drupal feature of setting different image sizes for different display builds.

I am not a fan of the Commons view of blogs (/blog/1) where the full size image is in the teaser view. And in D6 you can't have different content in the teaser.

I know it is confusing, but when I enable multiple images and use insert, I set the field to only display the first image in the theme.

D7: field--field-image.tpl.php

if ( ($element['#view_mode'] == 'full' || $element['#view_mode'] == 'teaser') & $element['#bundle'] == 'article') {
  $items = array_splice($items, 0, 1);
}

Are people happy with the rich-text input?
