Blurry images

Hello Support,

I purchased today additional variation images… It works well — one thing i couldn’t figure out is why the gallery image are blurry? Ex: https://boosblocks.4dd-workspace.de/product/pro-chef-hard-maple-reversible-cutting-board-with-grips-and-juice-groove-46x31x4cm/

Could you please help with this?

Thanks.
