How can I change the background of the product image?

[loveordie]

My website is ohmycos.com,

I have changed the theme of the website to white color,

then I uploaded the product image,the background of the product image is white,

but after I uploaded the product image,the background of the product images wasn't white on the website,

it looks like there is another gray background image on the product image,

How can I change the background of the product image?

I do not think the background is related to PrestaShop.

I think it is from your original images. it seems that your product image is scanned from old photo. you need use image processing soft to remove the image background first then upload to PrestaShop.

Thank you for your reply,it's my first page,and my first image of every product,I had set the white background,but it looks like there is another gray background on the image.

I tried to use another white image to replace the product,but the white image still shows a gray background,I don't know how to change it.

the original image is this

and the blank image built by photoshop with wite color,shows like this,it's also gray.

I tried to change the product.css with the method on google,but it doesn't work

here is my product.css

you image is not pure white back ground. it is still kind of grey.

You may need to use image processing tool such as Photoshop to make it white background.

(if you do not know much about image, it is better to have someone know it to do that for you).

Thank you for your reply,but it is the image I built with photoshop,and the background is pure white,I had tried web color white and RGB color white in photoshop,but it didn't work on my website,I think maybe there is a gray background in my product.css,but I can find it.I can't work it out.

Hi @loveordie,

I have the same problem: pure white images created by Photoshop or illustrator are rendered with some tiny grey lines.

I found an answer there https://prestashopturkiye.com/white-background-of-square-images-has-feint-grey-lines/ but it did not work

Did you find a solution?

Thank you
