Currently, when a photo selection is submitted in PAM, the only acknowledgement / confirmation of the selection is that the "OK" button is now black and therefore selectable. I do not feel this is enough of a confirmation for users (even I was thrown by this and made my selection again to be sure).
-- JP suggests that in lieu of the gray “Launch” button we have a plain white box that says “tap”, etc. and once a picture is successfully submitted through PAM, the box is then filled-in with the photo that was selected. JP has used this in the past with other apps. I find that it’s a gentle confirmation of the selection.
-- Also JP alternately suggests that whatever button was there initially could simply be replaced by a checkbox with a check in it to acknowledge the successful selection.
