------Solution--------------------
Ecshop itself does not support BMP image generation thumbnails. You have to convert to Gif/jpg/png first one of them.
------Solution--------------------
You can download a imagecreatefrombmp.php
and change your program.

All I want is for ecshop to support this generation diagram! What do we do?

Includes/cls_image.php is Ecshop's image processing library, you can use imagecreatefrombmp this function to expand itself
