Question: using image with separated field

Hi!

I'm producing a japanese animation review website and I have one question...

Using CCK, I create the "review" content type, with all the particular fields. I want to add a screenshot, but I want to add out of review text, into a separated field, that upload and save the image related to the content id.

For example: today I want the screenshot aligned to the left... To next layout, maybe, I will want to set to the right. How I can do this without edit all reviews?

The module "movie review" isn't compatible with my version of Drupal (6.x).

Thank you.
