Hi,
I am also talking about frontend listing as well
As I said, the system can create different thumbnails for different places where the images have to be displayed. For the frontend listings, edit the settings of your menu items/modules via the Joomla menus/modules manager and you'll find "image width" and "image height" settings to change the size you want for each menu/module.
Do you mean when we add product and upload image in admin it always create 100x100 thumbnail not according to settings ? If you are correct then there is no way to change the thumbnail size in admin apart from making changes in code ?
That's right.
Moreover if we make changes in code it will be overwrite when we update the hikashop
Yes, you'll loose the change when you update if you do it like I said.
What you could do is use a template class override:

But I wouldn't bother for the thumbnail size of the uploader system in the backend... It won't change anything to the images on your frontend anyway.
