If anyone want to judge a person by a picture or telephone voice then they deserve what they get! Pictures can be photoshopped and of course a person would be foolish to submit anything but the photo that portrays them in the best light. It might be a picture from a year or even 3 years ago. In addition, imagining what a person looks like from their phone voice is also very misguided.
But if the shadchan needs a photo to remember who they met and spoke to, that is another issue altogehter.
