How can we send as attachments photos of an subform upload field?

I have a subform with name Photos and a subform upload field with name Camera_Photos.

I would like when someone adds photos in these subform then to send these photos as attachments in an email using the sendmail function
Does anyone know how can i do it? For example if we add 2 photos in the subform upload field then these photos to be sent as Email attachments.

The sendmail should be something like

sendmail  
 [  
    from: zoho.adminuserid  
    to: candidate_email  
    subject: "Subject Text"  
    message: "We welcome you aboard. Here's wishing you a great career with us."  
    Attachments :file: fileResp, file: fileResp2
 ]


but I do not know how to write the loop inside the Attachments option

I think it is something with the collection variable in a subform. Something like file:<collection_variable1>.<file_upload_field>...
