Looks like something is missing in your database.
Did you check the Bakery upgrade log and save a copy? Please post.
If the upgrade log is not available any more, please check your database using phpMyAdmin or similar. There must be a table named [PREFIX]mod_bakery_images. If not, create it by running the SQL query below in the SQL tab of phpMyAdmin. Make sure that you have changed the table prefix "wb_" to the one defined in your WB installation.
CREATE TABLE IF NOT EXISTS `wb_mod_bakery_images` (
`img_id` int(11) NOT NULL AUTO_INCREMENT,
`item_id` int(11) NOT NULL DEFAULT '0',
`item_attribute_id` int(11) NOT NULL DEFAULT '0',
`filename` varchar(150) NOT NULL DEFAULT '',
`active` enum('1','0') NOT NULL DEFAULT '1',
`position` int(11) NOT NULL DEFAULT '0',
`alt` varchar(255) NOT NULL DEFAULT '',
`title` varchar(255) NOT NULL DEFAULT '',
`caption` text NOT NULL,
PRIMARY KEY (`img_id`)
);
