Hide image for some products

I want some of my products to NOT require a image, i.e. hide the image

Hi,

The images are not required on products. But if there is no image, HikaShop will display the default image.
There are different solutions possible but we have to know more about your requirement in order to give you the most appropriate solution.

What do you want to do exactly ?
How do you want to make the difference between a product with and without an image ?

Regards,

When I do not choose an image for a product, I do not want an image to display, just the product name.

...and no default image

For the listings, you can edit the file listing_img_title of the view product via the menu display->Views and change the line:
if($this->config->get('thumbnail',1)){

to:
if($this->config->get('thumbnail',1) && !empty($this->row->file_path)){

For the product page, you can change the line:
} else {

to:
} elseif(!empty($image->file_path)) {

in the file "show_block_img" via the menu display->Views
