Hi @manticarodrigo,
Thank you for the review ??
Currently, the plugin email templates do not add product images for the products. However, if you wish to add the images, it is fairly simple to achieve the same.
These email templates can be customized the same as any of the WooCommerce email templates.
Please copy the email template using the WooCommerce->Settings->Emails->Send Quote->Copy file to theme button into your theme folder. Once done, you can customize the email template as desired.
Updating the plugin to future versions will ensure that the customized copy is not overwritten.
I hope this helps. Please let me know in case if you have any further queries.
Thanks,
Pinal
