how to reduce the size of images

Thanks for the answer but the video doesn’t help too much
What I need is to have 4 columns with not too big images.
Let say half screen size but with big space between the columns.
If I try to select 4 columns I have the first and last image cut in the middle but if I select 5 columns everything is perfect but with few space between.
Please help

Thanks for the reply.
i found that the margin is the only way to reduce the image size, this is the reason why I used huge margin for items, but if there is another way please let me know.
Thanks also for the slider center set up, now is perfect with 4 items.

I have another question: is there a way to copy a WCPS? This can help a lot when you need to create specific slider for each product where you take out only the product that is already on the product sheet.
I use to put a slider where I show the other products from the same producer and of course don’t make sense to put on the carousel also the product that is on the sheet
Many thanks

Thanks for the suggestion, the plugin is perfect

I have another question regarding the “add to cart” button.
I see I can create margin on it but there is no way to put the buttons at the same line.
Everything depend by how long is the product name; but if I have product name with very different length my buttons can be up and down and not on the same line.
Is there a way to fix this?

Many thanks
