Images dont resize

Which theme is this regarding?

videozoom from wpzoom. why? Is that a theme issue?

Have you asked your theme’s vendors for support with this?

Typically yes. Images don’t resize unless the theme is responsive and supports that.

Can you tell me the file where that coding is in the usual themes? I’ve tried to contact them but they didnt answer so far.

I’ve found that that is the script itself that cuts the image that streches it. where is that made?
