Post real life people in the people category and not in general. Also high resolution is not the same as high quality. A lot of your walls have issues with jpeg compression most likely caused by upscaling.
404011xz so i would like to know can i upload the real life people photos with good quality, is that allowed. thanks in advance.
If they are good quality then yes. I'm not sure if you upscaled them on purpose or not but the vast majority of the walls you posted had horrible jpeg compression and pixelation in them. If you did upscale them then it's a rule to upload the original resolution when possible.
404011xz oh im extremely sorry for that but i don't intentionally want to do that, i will definitely upload the original, good quality photos from next time. thank you for your response really appreciate that.
