thumbnail would be larger than original)

Hello @mdnazmulislamnil,

If I get this right, all your thumbnails get regenerated but these two, is that correct?

WooCommerce also has its regenerate functionality built-in. Can you take a look at it in case something is conflicting? As far as I know, Woo should automatically resize images on a theme switch or when the sizes change.

yes not generate just these two but these size also generated if I use Smart Image Resizer plugin but without this plugin it not generate

Hello @mdnazmulislamnil,

Thanks for reporting this. If I still get this right, this looks to be the intended behaviour from the Regenerate Thumbnails plugin.

The Regenerate Thumbnails plugin intends to, in fact, regenerate thumbnails, which are supposed to be images more minor in size than the original (as per the definition for thumbnails).

It sounds like you want the plugin to upscale the image to the size required by WooCommerce, which it’s not within the plugin’s functionalities. Hence, the error you’re seeing: “thumbnail would be larger than original”.

There are two options for you:

1. Reduce the size of the image for WooCommerce on the customizer, as per this link.
2. If it is not available there, look for an option in the theme or somewhere else (other plugins, for example) to reduce the image available.
3. Or, send higher-quality images, larger than 2233×1035 px.

There’s nothing the plugin can do to just upscale the image in a way that would make you happy, in this case.

Hope it helps!
