How does Image Reference block work?

I have this exact same question as well. Any help would be appreciated.

-Gman

Which module provides this block? Acidfree?

The reason that you have not seen it is because the block does not work without mod_rewrite.

        $uri = parse_url(request_uri());
        $nid = array_pop(explode('/', $uri['path']));

results in a empty nid without mod_rewrite and in cases when the last argument in the url isn't the node id.

If you look how it's done in the profile.module it seems that the node id can be retrieved with arg(1). If you replace the lines above with:

$nid = arg(1);

It should work. But then it seems img_assist_get_references also does not function. This leads us to img_assist_map_load which uses the query

SELECT * FROM {files} f INNER JOIN {img_assist_map} i ON f.fid = i.iid WHERE f.nid = %d

which returns no results, because it should be

SELECT * FROM {files} f INNER JOIN {img_assist_map} i ON f.nid = i.iid WHERE f.nid = %d

And voila! The "Image reference" block in all its glory! Enjoy :)

This should be turned into a patch and submitted to the img_assist module. But to make it a good patch, what is the recommended method for retrieving the node id from the path?

Want to make those changes (for 5.x) and don't know if you are referring to the img_assist.module or another file. Can you let me know?

Thanks,
