How disable prestashop image compression

[seog]

Hi

 

I had compressed with good software my all product images due to SEO purposes and the absurd image compression of Prestashop has worsened the quality of images and especially has multiplied by x 3 the size of all images

 

How can I disable fully the .jpeg compression in Prestashop when I upload a csv?

Probably not easy without creating other issues. The file ./classes/ImageManager.php would be your friend.

The problem is: This class does creation and resizing for all kind of images. Resizing always means, a new image is created. And for JPEG it means, there is a compression needed in order to create the image.

 

In terms of product images, there are several versions and sizes created after uploading. They are named like

-home_default.jpg

-large_default.jpg

-mendium_default.jpg

-thickbox_default.jpg

plus the original version.

 

The PHP function called is named imagejpeg. It's call is appx. on line 550.

 

The better solution could be to change the .tpl files related to image display and there grab the original file instead of the prestashop default, which is a resized image. However, if you would forget to resize your image before upload, the size displayed would be the original size then.

Hi Scully@

 

Thank you for your answer,

 

Do you know say me what could be the right path for load only my original images without PS compression (uncompression) in product page ?

The original code is src="{$img_prod_dir}{$lang_iso}-default-large_default.jpg"

 

 

best regards

The path does not change. Try this with just leaving the fixed part away. Check the source code of product page if the image wouln't show up.

src="{$img_prod_dir}{$lang_iso}.jpg"

Didn't work isn't a poor answer.

Did you get an error message?

Did you check the source code?

What does the source tell you?

This code load same image uncompressed... Tested in product.tpl

 

If you get load product image with different codes/variables, it always will be uncompressed

 

The issue I think is in htacces rewrite rule:

RewriteRule ^([0-9])(\-[_a-zA-Z0-9-]*)?(-[0-9]+)?/.+\.jpg$ %{ENV:REWRITEBASE}img/p/$1/$1$2$3.jpg [L]
