where to adjust the image size of " manufacturer product list "

[Mr.Curiosity]

Where can I adjust the image size of my manufacturer product list?
I have trying to look in global.css and productlist.css but I couldnt find it.
I am using PS.1.4

You can change the generated image size at back office

Preferences tab - image sub tab

But please note this change also applies to product and other images.

I suggest to just change the image displayed size(not physical size) in the theme file of manufacturer page.
it is here:

YourSiteRoot/themes/YourSiteTheme/manufacturer-list.tpl

for product images here
YourSiteRoot/themes/YourSiteTheme/product-list.tpl

I have no luck with my image size of manufacturer list.

I modify from this

<!-- logo -->

                   {if $manufacturer.nb_products > 0}getmanufacturerLink($manufacturer.id_manufacturer, $manufacturer.link_rewrite)|escape:'htmlall':'UTF-8'}" title="{$manufacturer.name|escape:'htmlall':'UTF-8'}">{/if}

                   {if $manufacturer.nb_products > 0}{/if}

<!-- logo -->

                   {if $manufacturer.nb_products > 0}getmanufacturerLink($manufacturer.id_manufacturer, $manufacturer.link_rewrite)|escape:'htmlall':'UTF-8'}" title="{$manufacturer.name|escape:'htmlall':'UTF-8'}">{/if}

                   {if $manufacturer.nb_products > 0}{/if}

but I dont see any changes..

also, my image size of my manufacturer is width 129px and height 129px.
but this size cannot be found in global.css / product.css / productlist.css / manufacturerlist.css and preferences>images
so I am abit puzzled here.

[shokinro]

the image size is not defined in css file. it is defined in PrestaShop database.
you can see this from the code

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

but I dont see any changes..

It could be cache issue.
Please set as following

back office - preferences - performances

Smarty
force compile -> Yes
cache -> no

There is another cache setting in the bottom, also disable it.
after that you should be able to see the changes
