Good way to force WP to show full posts not titles

[auspiral]

I'm working on a product site, and most themes I like fail to show the whole post in category or tag listing pages.

The homepage looks great, but after clicking on a category or tag, I get a list of posts with a short exerpt, and for this site I really need to have the product image show up.

It seems like this is coded into each theme seperately, anyone know of a good way to do this, plug-in or WP hack, I'm up for anything at this point.

Thanks

looks like you can manually change

the_exerpt()

to


the_content()

in categories.php and archive.php in your theme 's directory
