I miss the possiblility to assign a "Post Fields/Image" (or "Post Fields/Custom Field/File Upload") to be a post-thumbnail.
I'm not a Wordpress coder, but it seems that post-thumbnail just a specific kind of
Custom Fields, so adding this feature could not be a big problem?
Thanks

It is a planned feature. It won't be in the 1.5 release but we do plan on adding this capability.
This is a feature I'd very much like to see added, espeically as the Featured Image / post-thumbnail function is now becoming ubiquitous in WordPress themes and people are using them for all sorts of new things.
At this point I'd settle for a hardcoded add-on to slot into the existing plugin files to add a new option under Post Fields for Featured Image.
There's a solution right here that works perfectly. Just copy, paste into functions.php and you're flying:

I have tried adding the code from http://forum.gravityhelp.com/topic/auto-setting-the-the_post_thumbnail?replies=6#post-17879 to the functions.php file of two different WP 3.1.1 installations with different themes and get the dreaded white screen for both until I delete it. Any insights?

Hi,
Same problem here as DesignWerks. I get a white screen using WP 3.1.2. Does the above code need to be modified for 3.1?
EDIT: Figured it out. The function set_post_thumbnail has been added to Wordpress core as of 3.1 (http://core.trac.wordpress.org/ticket/15192).
Just change the name of the function and it works again, eg.
add_filter("gform_post_submission", "set_gform_post_thumbnail", 10, 2);
function set_gform_post_thumbnail($entry, $form){@Jelle Make sure you are running the latest version of WordPress. That filter uses a built in WordPress function so it shouldn't be undefined unless you are running an older version that doesn't have it implemented.
You would want to place the code in your themes functions.php file. That is where custom code typically goes.
Hi bgdan,
This would be a bit trickier than it sounds. The featured image has to be an image that is attached to the post. As far as I know, an attachment (image) can only be attached to one post. This means you'd have to handle generating a new category-specific attachment (image) every time you created a new post.
This would be probably be much easier and make more sense to handle this from the template side of things. You can create a category-specific custom field and then created a custom template to display these posts and use the custom field value to determine which image you display.
