I upgraded my Magento from 1.5.1 to 1.7 using a fresh install as described here: http://www.customerparadigm.com/magento-development/upgrade/how-to-upgrade-magento/
For some reason my product images and extensions are not showing. I refreshed/flushed all caches, and reindexed.
Any idea why this might be?
I did run Magento/login to admin before copying the extension and media files over, but I am not sure if that should impact it.
