This is the only hack you need to have for the category images. This hack will take care of the image while upload or do it dynamically from the frontend, putting a settings on the backend. Since this is an ultimate hack, it construct with several files and line of code to complete this hack: so please stay close attention.

Files we are going to work with

administrator/components/com_virtuemart/classes/ps_config.php
administrator/components/com_virtuemart/classes/ps_product_category.php
administrator/components/com_virtuemart/languages/admin/english.php

								'param1' => $temp_file
							);

if( empty( $d[$field_name] )) {	
	/* Return new image file name */
	$d[$field_name] = $to_file;
}

replace with

if("full image" == $image_type && '1' == PSHOP_CAT_UPLOADING_FULL_IMG_RESIZE_ENABLE) {
	$fullresizedfileout = $path.$to_file;
	$vmLogger->debug( 'full image file name = '.$path.$to_file );
	$vmLogger->debug( 'temp full image file name = '.$temp_file );
	if( !file_exists( dirname( $fullresizedfileout ))) {
		mkdir( dirname( $fullresizedfileout ));
		$vmLogger->debug('Created Directory '.dirname( $fullresizedfileout ));
	}
	$resizedFullImage = new Img2Thumb( $temp_file, PSHOP_CAT_UPLOADING_FULL_IMG_WIDTH, PSHOP_CAT_UPLOADING_FULL_IMG_HEIGHT, $fullresizedfileout, 0, 255, 255, 255 );
	$fullresizedname = basename( $fullresizedfileout );

Great solution!
But that is still found useful hack for the category list (browse_page).
What do you think?

Greetings!

  I am not sure what do you mean.
  Can you send me a reference or some guideline of what you mean.
  I will be happy to write a hack for it.

  Thanks for your comments.
  We are facing this everyday with all the clients that are using Virtuemart.
  We come to love and hate with it.

Great idea! I hope you can help me. I do not see the 'layout' screen shots you show, and I have tried applying all your suggested changes but I see no difference – the 'Harps' category in harpsonline.com still shows no images and the admin category page still shows the same very few options.. I am new to Virtuemart so maybe I am looking in the wrong place. I use Virtuemart 1.1.4 (in Joomla 1.5.15). Is this a different version to the one you use?

Sorry, I DO have the layout screen you show above (ie. your 'after' shot). I was looking in the wrong place. (I have a lot to learn in Virtuemart!) Now…. my Harps category contains sub-categories, but no products. Will your hack enable me to display an image for each sub-category? Or a single image for the Harps category? The website is http://www.harpsonline.com.
Thankyou!

Hi Designersandbox! I have your hack working well today. It is wonderful! Thankyou for your solution.

Thanks a lot !

Some precisions:

The last file, categoryChildlist.tpl.php, is located in /components/com_virtuemart/themes/default/templates/common

Also, it seems like the first time we go into the Configuration > Site > Layout part of the VirtueMart control panel, there are constants written in the width and height text boxes (some text in capital letters). In order to enable the features that this hack allows, it is required to check the appropriate check boxes, but also enter a numerical value in the width and height text boxes.

I hope this can speed up the implementation for future visitor

Thanks again to whoever did this !

This is a really good hack, but I'm facing some problems when I try to upgrade from an older version to a latest one.

hi sandbox,

i gather that the hack above allows you to have a thumbnail for the browse page which is different in size to the thumbnail on the flypage?

i have tried all sorts of combinations, checking and unchecking boxes, etc but no matter what i do, both thumbnails come out the same size

I followed exactly the instructions.
However, the category image won't change in size whatever I try.
GD is enabled and I also see my CAT_FULL_IMG parameters in virtuemart.cfg.php .
Perhaps this hack doesn't work with version 1.19 ?

It worked on some sites for me, but doesn't seem to work on my last 2 sites – must be because of an upgrade. It won't let me save anything under the configuration. Each box just keeps saying "PSHOP_CAT_FULL_IMG_WIDTH" and variations. I put in a number, check the tickbox, click save or apply and come back to the screen and it hasn't saved anything. Everything else on this screen saves, just not the settings for this hack.

Where is this info being saved? In the database? If so I'll put the width/height into the database itself if I have to, because saving it in config won't work. Joomla v1.5.22, VM v1.1.9. Any ideas?

Sweet fixed it for anyone else who has this problem, I entered the figures directly into administrator/components/com_virtuemart/virtuemart.cfg.php

This part here:
define('PSHOP_CAT_FULL_IMG_RESIZE_ENABLE', '1');
define('PSHOP_CAT_FULL_IMG_WIDTH', '170');
define('PSHOP_CAT_FULL_IMG_HEIGHT', '199');
define('PSHOP_CAT_UPLOADING_FULL_IMG_RESIZE_ENABLE', '');
define('PSHOP_CAT_UPLOADING_FULL_IMG_WIDTH', '170');
define('PSHOP_CAT_UPLOADING_FULL_IMG_HEIGHT', '199');
