Hello, I´ve been trying to uplod my photos but I can't

The first image is almost a full stop underexposed and is blurry. The white stopper doesn't show up well against the white background, and the bottle should have been larger in the frame. The snake image is very blurry with messy edges. Neither of these should be in PNG format since they don't have transparent backgrounds.

The pictures have quality issues:

The first is noisy, and not sharp.

The second is also not at the correct quality level.

(Blown out highlights)

(unsavoury scraps, possibly from a failed cut-out)

There are other issues with these pictures. If you are new to stock, you should consider these resources: https://helpx.adobe.com/stock/contributor/tutorials.html
