In my local machine it works fine but in live server get error:
TCPDF ERROR: [Image] Unable to get image: http://lwstudios.co.uk/images/stories/virtuemart/product/resized/pack4.jpg
Joomla version - 2.5.16
PHP Version - 5.3.28
Virtue Mart - 2.0.6
Are those really your versions? http://forum.virtuemart.net/index.php?topic=118683.0
Are you trying to show product images in the invoice? That is not a default VM function.
I have the same issue with invoices randomly not created.
TCPDF ERROR: [Image] Unable to get image: http://www.mywebsite.com/images/stories/virtuemart/shipment/parcelforce.png
Joomla! 2.5.24 + VirtueMart 2.6.10
the tcpdf library seems to gag on png's - try a gif or jpg for your ship logo
Thanks, I'll try that. Is happen randomly anyway, not all the times.
In meantime I updated to Joomla! 2.5.27 + VirtueMart 2.6.12.2
