Why does Prestashop not set image sizes to images?

[HavanA]

There are a few topics on this forum regarding image size and the remarks that shop owners get from GTmetrix about the missing image sizes.

 

When I uploaded the images, Prestashop made several copies like thumbnail, small images etc.

 

What is the reason that Prestashop does not automatically add the image size to these copies?

 

 

I seem to have pictures in folders that cannot be found in cpanel via filemanager, e.g. I have a pictures in www.myshop.com/34-home/pictures.jpg --> but the file '34-home' is not present?

actually, the size is set in your html only if it's available as variable. For example, in the homepage, the homefeatured block has this

 

height="{$homeSize.height}" width="{$homeSize.width}" 

 

Now obviously if the homeSize variable is not set, sizes will be left blank. You can also hardcode them in your theme, if you prefer, so that you solve the issue with gtmetrix

[HavanA]

So it is correct that here in this report of GTMetrix, all these images do not have image dimensions in the html code?

( http://gtmetrix.com/reports/www.inktoutlet.nl/MMmvvVHD ) Or do I misunderstand?

 

I would also like to understand why these images come from files that are not on the server --> if you look at the report you see that images come from ../129-home_default/...etc.  And these images are missing the dimensions. Is there a code missing on my pages or id this supposed to be like this (no image dimensions and these folders like ../129-home_default/.. etc)?

[NemoPS]

But this is on the server, I can access it

Yeah, it's code missing on the page

[HavanA]

Yes, but I cannot see the file via the file manager in cPanel; so that confuses me.

 

And is that supposed to be that dimensions are missing, so shop owners should add them manually?

[NemoPS]

ah, because it's rewritten, that is not the real path

 

And yes, if they are missing you have to add them manually to the template

[HavanA]

ok, thank you for explaining this!

Which .tpl file should I edit for the manufacturers products pages (the pages that show the products for the chosen manufacturers)?

 

[NemoPS]

It should be manufacturer.tpl

[HavanA]

Well, yesterday I looked there but I could not find any code for these images, like e.g. there is in product-list.tpl.

I did look for "<img src=" with missing "height="{$homeSize.height}" width="{$homeSize.width}"  but couldn't find any in that .tpl file?

[NemoPS]

Yes, in the end product-list.tpl is shown on that page too. so that is the file you need to add sizes to!

[HavanA]

Correct, in product-list.tpl on line 40 and 41 the dimensions are specified:

<a href="{$product.link|escape:'htmlall':'UTF-8'}" class="product_img_link" title="{$product.name|escape:'htmlall':'UTF-8'}">
					<img src="{$link->getImageLink($product.link_rewrite, $product.id_image, 'home_default')|escape:'html'}" alt="{$product.legend|escape:'htmlall':'UTF-8'}" {if isset($homeSize)} width="{$homeSize.width}" height="{$homeSize.height}"{/if} />

So that is why I do not understand it does give the warning on GT metrix? Because in non-manufacturer products lists this warning is not given. And the homeSize.widt is the 124x124, correct?

[NemoPS]

It might be that homeSIze (the variable) is not assigned on that page, I can't remember right now so you can even hardcode that if you prefer! And yes 124 is the default one

[HavanA]

Well, thanks Nemo. I now hardcoded it, and the warning is gone.
