[support] webform image upload - Where is kept in database?

HI guys, I am working with webform and so far so good but I am having the problem that when I createa form using webform and the form has a image upload I can not find the image url in the table. I know where the images are on the server but nothing tells me which image goes with which submission. If I edit the submission it shows the image path or URL but in the table where do I find this. I do not see it in webform or webform_submissions o webform_submitted_data tables. Where is the image url kept on the table? thanks!!!
