[Theme Horse Support Team]

Hi @bangtran-toji,

Thank you for liking our Theme.

1. Sorry we don’t provide the support on editing the images. We only provide supports regarding theme elements, Issues and bugs through codes.
2. Yes NewsCard Pro supports Adsense ad Placement using the common and simple Text Widgets on Widget area.
3. Yes we haven’t coded to resize the images into smaller sizes. Every images with any sizes gets fit and covered in theme layouts. The Website Speed is not much affected but yes to control website speed on any themes you can use the compressed images to upload in your site. You can find many Image Compressor Sites online to compress the images and they will not even affects the quality of images. Like we can use https://compressor.io/ to compress your images before you upload to your site.

Thanks
