Why My images is not accepted in adobe ? Looking for a vaild reason

IMG_1537.png & IMG_15225.png - uneven, splotchy background with dust spots; not sharply focused. Jewelry designs might be copyrighted, so unless you're the designer and can provide a product release, you probably would have gotten rejected as an IP violation if these weren't rejected for technical issues.

IMG_1805.png - You need much better lighting to effectively photograph jewelry in order to prevent the hotspots you're seeing here. The jewels need to be immaculately clean as well as the background because every smudge and dust spot shows up.

I viewed th first two images.

Both images are out of focus and are under exposed. Also you need a IP release from the person who create the design of tze jewlery.

Adobe TOLD you the basic reason. We may be able to guess more details, but please tell us their reason, so we don't waste your time with bad guesses. You will of course need an IP release from the maker of each piece of jewellery.
