As I said, you can just send them the document(s) you already submitted, but with (probably new but certainly stamped and dated) photographs.
From
https://www.canada.ca/en/immigratio...l-file-processing/accepting-applications.html
It is not necessary for the applicant to submit a new application kit or to re-sign and redate an application every time an application is returned for incompleteness. If an application is signed and dated, not postdated or staledated, it is considered “locked-in” on the date that it is originally signed and dated. The filing date is used to maintain, for example, the original residence calculation. Therefore, the applicant(s) must provide the missing information and/or documentation and resubmit the same application.
(underlining mine)
So you should just resubmit the same documents (i.e. the stuff you submitted originally) but add the stamped and dated photographs.
I would add a letter explaining that you are resubmitting your application and have corrected the issue with the photographs.
