Image comment submission: where is the image path to put in?

If i select submission type "image comment": where is the image url to setup?
Maybe i'm not fully understand both of submission procedure and GUI, but: i've found, where to setup the

• page URL,
• keywords,
• link anchors - primary and secondary,
• image subject,
• image comment,

but not - the image url (or image path)...

On the following screenshot is the managing screen with only "image comment" as submission type - could somebody point me, where on this screen (or somewhere at other place) is the image url to setup or image path to provide?


thanks

That type of site is doing a search for already present images linked on sites and post a comment to it.

ah, understand, thank you!
