<blockquote>Is there an automated way within the Joomla Admin CP to upload and/or change the images in this slideshow that are attached to links. I had to manually resize both the larger image and the thumbnail images and then upload them to a rouge directory via FTP. It’s very clunky. Is there a streamlined way of doing it that I’m just not seeing?</blockquote>
dont do it. Pls open your module at:In Admin panel, go to Extensions >> Modules Manager and click on module name (JA Slideshow 2) to go to configuration page. and checkp paramet a right side. U can see,
# Thumbnail Width: Width of thumbnail (if you choose thumbnail option for Navigation)
# Thumbnail Height: Height of thumbnail (if you choose thumbnail option for Navigation)
# Main Item width: Width of main item
# Main Item height: Height of main item
edit it
