Hi,
I presume you wish to have the logos placed on the left hand column of your site i.e. where your categories menu is?
If so you can open up [skin1]/customer/home.tpl and locate the following:
{ include file="customer/categories.tpl" }
paste this below the above line:
Code:
[img]{$ImagesDir}/name_of_your_image.gif[/img]
As you will see rather than using the absolute path to your image everytime, the {$ImagesDir} variable maps to the [skin1]/images folder by default. You will therefore need to ensure that any images you add use the variable '{$ImagesDir}' and that images are located in your [skin1]/images folder.
