Multiple image styles Is there a way to take multiple style image for one image field?
I want to use a 150×150, 180×180, and a 300×300 style at the same time.
If I understand your question correctly, you'll want to use the ImageCache module. This is in core as of Drupal 7. Try the documentation for Drupal 6 and/or this screencast if you need help understanding how to use this module.
