zip download permissions are wrong - cannot open files

when I download several photos from my phone - as a zip archive - and extract the archive, I cannot open the files. I don't have READ permissions.
zipinfo on the archive gives (an example) :

zipinfo '/home/rick/Downloads/Photos.zip'
Archive: /home/rick/Downloads/Photos.zip
Zip file size: 10485590 bytes, number of entries: 3
