It's really strange: as I said, I substituted all the nophoto.xxx (.jpg and .gif) images.
You can see at this page:
testfrogsoftware.net/vectiswebk2c/
that I inserted a new item, that shows different images according to what module I'm using it into.
'Ultimi Articoli' is a SO K2 Slider, and it shows the righe image, even if it's totally wrong, there is some elaboration that doesn't behave well.
Downl along the page, on main content (rendered with a SJ Mega K2 News), category Servizi has as first item just the same, but the image is now the original SmartAddons nophoto.
The item is called 'Sportello unico consumatore', by the way, and the item was created obviously after the image substitution.
Thanks again.
