Hi,
In every Virtuemart version, the line number might be changed, but the codes are always the same. By looking at the most recent Virtuemart version (vm2.0.26) I found the line numbers for you.
Tutorial1:
flexiblewebdesign.com/forum-virtuemart-2-template-support/1409-tutorial-1-show-manufacturer-logos#6660
Look at the lines starting from 1005th (with VM2.0.26)
Tutorial 2:
flexiblewebdesign.com/forum-virtuemart-2-template-support/1410-tutorial-2-multiple-thumbs-in-category
Look at the 119th line (on VM2.0.26)
and do the necessary changes.
If you like the same look as our DEMO, you would need use the same Joomla Template that we used in the DEMO. We have used Official Gantry Joomla Template. It is a free joomla template and can be downloaded from:
www.gantry-framework.org/download
Regards.
