I was doing research to fill the Digimon Survive character wikis and I found smaller, transparent versions of images I’ve already posted.
These posts are:
Syakomon post #3430397, Floramon post #3429180 and Lopmon post #3428648

The transparent versions are:

Lopmon: https://digimon-sur.bn-ent.net/images/character/c06/c06_1_06.png

The transparent images have a smaller resolution (about half the dimensions of the originals).

I don’t know how to proceed from now.
Should I request a replacement, flag my own posts as lower quality, or simply make the transparent images children to the white background ones? I could also abstain from posting them if the smaller resolution poses problem.
I would like advice so I can know what to do, please.

Transparent images aren't usually a big deal on this site, even when talking about official art.

I don't think a transparent background is worth a drop in size.

Judging by post #1638823, post #1638813 and others existing, there might be high-res transparent PNG versions of these somewhere.

Even though the transparent ones are smaller, they do at least lack the JPG compression. I'm only using my phone right now so I can't properly compare the PNG vs JPG versions.
