Don't bother with the full version
If you pay for the full version to get the hi res version, don't bother. First of all the so called hi res version is not much more detailed. Secondly, and worst of all, the hi res version not only is not included in the full version by default, meaning you have to manually click to download it. Then when you think it's now saved on your device, NO! The next time you want to use these again it's back to low res mode!
