Even if the changes are small as an open source project you deserve to get credit for your contributions.
If you like & have time do a gitpull with the changes to src/qt to show Photon instead of Bitcoin to the Photon source code. Once tested I will also merge your work.
If Bluedragon & I author these changes it looks to the world like we wrote them.
I always prefer to give credit when possible.
For dependencies did you use qrencode 3.4.3 ?
I would be curious to see the changes you made to the .pro file.
If you are busy and don't have time it's cool too / Thanks for helping out !!
