Hi there,
so i think i got a simple Problem......
I want to change the Picture of an Item i Sell in my Shop.
Want to edit the picture of the "Grub"
Anyone got  a hint how to do this ?
Regards

Also if i put Grub in the GUI shop, it always tell´s me "Item not found"

if you set an image link in the URL it must always have a shortname in the shortname field to work.

so basically if it is a custom item ( none game item ) just make up a name to put into the shortname field.

Also, I don't seem to have that problem but the grub item should have auto been added to your config already so all you should have to do is add it to the shop in a string like 

"Grub",
