Hi, please help me to reduce the blank space between the product image and the price and title in the module latest product. You can see in the attached image.

I tried with this CSS code: div.hikashop_product_image {height: auto !Important;} but when the page load at first time there was overlapping.

Thanks in advance!

Sorry Nicolas! Thanks to attached the error. Now, you can see my page. Thanks for you help.

Thank you so much Nicolas that is the problem, but i don't understand how its work. Could you tell me where do i have to configure the image size in hikashop?

The original images size that I uploaded was 500x500 pixels. Then I configure in configuration/main/images: Thumbnails 100x100, product images 300x300. Then I had the images size in the hikashop content module 500x500. I change the product image in hikashop configuration to 500x500 but the image of context module just can use 300x300 image.

In addition, I saw in hikashop images folder and there are folder for images 100x100, 300x300 and 500x500.

Right now it is ok with 300x300, but I would like to understand where can I configure the size of the images that I am going to show in the hikashop content module.

Thanks again!
