Edit: Seems there was an error when I unzipped the folder the first time which must have corrupted the file, its fine now I tried a second time. thanks for the help
Hiyah,

I have it selected and I’ve tested the image on my windows photo viewer and in Clip Studio and neither support the PNG for some reason, bare in mind I’m running Windows if that helps (as I notice the folder says Mac).

Sorry for the trouble.
