One picture was accepted and the other, with some quality, was refused due to quality problems. HI,I took some photos of a cup of espresso. As a variation I inserted a different national flag into the mug for each photo. I didn't upload the whole pack together, I first downloaded the flags of USA, Italy and Sweden and everything worked fine, all photos were accepted. Some time later I tried to upload others, for example Norway, Denmark and so on. The quality was absolutely the same, the colors and resolution were the same, without A.I. usage, the only thing I changed were the flags, but Ad Stock rejected them saying there were quality issues. I fear that some algorithm did not notice the difference between the flags and rejected the images due to a misunderstanding. Other photos of mine were rejected but the reason was clearer and I had nothing to say, but in this case I can't understand it.However, I have pasted one of the accepted photos and one of the rejected ones below. Judge for yourself.I hope the decision to reject them can be changed.Thank you for your attention and
