He is now 17, and image is from December 2019, so he was just a child then. Plus it's small in size, and blurry in quality.

how can we do if we can't find a way someone has a site where we can find photos of young players

We've already told you directly several times that in cases like this, no image should be requested. This is also explained quite clearly in the guidelines to uploading images.

If I spot a new account with the exact same behaviour, I'm going to keep banning you and deleting all your requests. Start reading and following the guidelines. I'm sick of you behaving like a stupid child.

they are of good quality the other photos requested

It's up to you to make sure that every image you upload is of good quality. I can excuse the odd borderline case here and there, but you've had around a dozen accounts banned for repeatedly ignoring the guidelines and requesting bad images. 

Every other member of this forum seems to understand the rules, apart from you. It's now time for you to behave like an adult because I don't have the time and inclination to repeat myself again any more.

it was a question

Then you should have put a question mark at the end. Whatever language you speak presumably has punctuation marks, right? My reply still applies nonetheless.

If you can't even formulate a question properly, no wonder you can't even manage to request images in the correct manner.
