I’m currently using AdGuard Adblocker chrome extension on the latest version of chrome and when turned on, their filter filters out my product images when viewing categories.
I believe this is because they have 300x300px dimensions which matches certain standard adverts. It might also be because of the ‘-300×300.gif’ last part of the file extension. I’ve only tested AdGuard but i’m sure others will do the same.
Is it possible to change the default sizes? 298px x 298px aught to do the trick. Might also need some core CSS changes to keep everything looking slick.
