I’m not sure, but I think I’ve seen it mentioned somewhere that one can pack the image textures into a .blend to make it a single file (and thus be rid of file path issues when sending it to someone else). Been looking a bit but can’t seem to find anything about it.
So I’m wondering, is this possible… or even very basic knowledge 
? or did I just dream it?
In the menu: Tools -> Pack
thanks 
that was exactly what I was looking for.
Seems I’ve been neglecting those menus, I thought that stuff could all be reached through the space bar.
