No not really you can't post pictures.
It may be the inlet washer has split.
It could be the silent plastic tube if fitted kinking mine did on my cistern not same as your though I snipped an inch off it its fine now.
it could be a filter if fitted.
I would first go for the silent fill plastic tube
then for the washer and fileter if it has one, you'll obviously have to turn the water off to the cistern first.
