How to change category thumbnail size?

[cooshti]

When I upload category thumbnail images they are resized to 180x180, but I need them to be bigger (300x300).

They are being uploaded (by default) to a folder ...  /media/catalog/category/resized/180x180/.

Can anyone please tell me how I can change this setting, as I cannot find anything in admin?

My Magento knowledge is not great, so a simple explanation would be greatly appreciated.

Thanks

This is how you display product image in phtml files (please ignore missing img attributes):

<img src="<?php
    echo  $this->helper('catalog/image')->init($_product, 'small_image')
            ->constrainOnly(false)
            ->keepAspectRatio(true)
            ->keepFrame(true)
            ->keepTransparency(true)
            ->backgroundColor(array(255,255,255))
            ->resize(135, 135);
?>" />

As you can see there's a handful of methods to modify product image among which is also a resize method. The code above resizes image to 135px x 135px. There isn't much you can do without delving into code.

Thanks for the reply, but I asked how to change the CATEGORY image (not the product), as below

When I upload a thumbnail image it is resized to 180x180.

I have checked via ftp and for each image I upload, it creates two resized versions in the following directories...
/media/catalog/category/squash.jpg

/media/catalog/category/resized/180x180/squash.jpg

/media/catalog/category/resized/360x360/squash.jpg

tI could be understood either ways. But anyway -- this post also contains an answer to your question (keep scrolling): http://stackoverflow.com/questions/8711253/how-to-resize-the-categories-images-in-magento
