Yes, ”Action Figure Broly” notice the difference in the image, before clicking “see options” and then on the product page, the thumbnail image before clicking “see options” is blurred, but after clicking, and being directed to the page the image appears in a much better quality.
This is how the thumbnail of that product appears to me: https://d.pr/i/ozLbmW
Perhaps I’m missing something, but it appears as good quality to me.
Looking closer at that element, this is the image that is being displayed: https://geekaoavesso.com/wp-content/uploads/2019/08/Frete-Gr-tis-8-polegada-20-cent-metros-Dragon-Ball-Z-Brolly-Broly-Figura-Anime-A-530×530.jpg
Which does seem to be less sharp. However, if I look at the original image that was uploaded (here), I can see the same thing: the image is not fully sharp.
So, it looks like this is a case of the quality of the original image not being ideal; or there being too much compression on the image. Are you using any special tool to compress or optimize images on the site?
