How to "delete" a user's photo in Spaces

Question

Hi,
When a user deletes a photo in his/her profile, I want to use a default photo to replace his/her photo. Can I pass in an empty string, null string or a default photo to setJpegPhoto()?
// ADFContext
ADFContext adfCtx = ADFContext.getCurrent();
SecurityContext secCntx = adfCtx.getSecurityContext();
secCntx.getUserProfile().setJpegPhoto("/tmp/LARGE.png");
Thank you.

Hi,
I’ve found another way to call setJPEGPhoto(). But, a problem is that when a user “yes” to delete, the photo is not refreshed and replaced by “LARGE.png” until the page is saved. Looking at the logs on backend, I know it’s replaced.
ProfileFactory.getProfileManager().getProfile(taskFlowUser).setJPEGPhoto("/tmp/LARGE.png");
When a user choose his/her new photo(upload), and “ok” it, the new photo shows up on the page before the page is saved. How is the Delete different from Upload for saving and refreshing a photo on the page?
Thank you.
