Despite having some experience over on Discogs with replying to others by including their comment(s) within bracketed quotations, pardon me in case things don't turn out the same here. Aside from yesterday and another post many hours earlier, this is the first time I am responding to someone here in the Forums section. Alrighty, on with the show.
"reason: quite a lot of noise should be shaper linea on her face"
Now ain't that real peachy! Right on the heels of what ZincRider said elsewhere, even a mere baby can see that photo was as good as it gets when it comes to present day images. More to follow further below.
"What does 'shaper' mean? Does he mean 'sharper'? What is a 'linea'? Does he mean a 'line'?"
It means that he can't spell to save his own damn life! I don't know about anyone else and will merely speak on my behalf. Unless it's some brain disorder or anomaly in my bodily wiring, I tend to be sensitive to that sort of shit(e). No, I don't go ballistic let alone apoplexy when I see grammatical errors and misspellings despite whimsically referring to myself as a grammar nazi extraordinaire. Keeping it simple, I just can't for the life of me fathom how some folks made it through years of school without having a proper grasp of basic writing skills.

I'm sorry but there's only so much that my brain's built-in spell check or grammar/syntax alerts can do without being overloaded like a transistor amplifier undergoing clipping. Okay, where was I?
"There are rarely clean images with flat colors. Most images are noisy. I am really surprised of denying, because its a simply perfect image..."
He pulled that horse crap with one image in particular that I will never forget as long as I live. I was kind of forced to grab it from AAX. It was basically a promo shot without any text whatsoever. I try as much as possible not to resort to AAX if I can help it, but since I couldn't find the same high quality photo online or the actual front cover image (AAX had nothing higher than 800px) I resorted to combining the best of both worlds: A much better one I found via Google Images at 953px and the following....

"My source is the original master-art. Its an 20MB-TIFF-File....I only resized it and saved it at highest jpeg quality. Please tell me: If the original digital master-art of an recent release is not of high enough quality, how can any image be good enough?"
Ahhh, there's your problem! You should have saved it in 5-D!!! Word has it that you know who is the only one in possession of that format.
To wrap things up, I don't know what else to say. All I know is that things better change -- and FAST(!) -- because if not this particular website is going to lose a good number of contributors. And no doubt take their business elsewhere.
