I'm trying to load an image from jpeg file and to add the material to the cube using the following code:

bpy.ops.image.open(filepath="/root/carteid_dini.png", directory="/root/", files=[{"name":"carteid_dini.png", "name":"carteid_dini.png"}], relative_path=True, show_multiview=False)

get material reference


mat = bpy.context.view_layer.objects.active.active_material


get texture reference


tex = bpy.data.images.get('carteid')


create node and assing the texture to it


image_node = mat.node_tree.nodes.new('ShaderNodeTexImage')
image_node.image = tex


mat.node_tree.links.new(image_node.outputs['Color'], mat.node_tree.nodes['Principled BSDF'].inputs['Base Color'], verify_limits=True)


cube = bpy.context.active_object


if len(cube.material_slots) == 0:
    bpy.ops.object.material_slot_add()


cube.material_slots[0].material= mat

When I run this code, the newly created texture is unfortunately not loaded and the image is not selected for the 'Base Color'.

Q: How to load an image from the disc and and assign it to an arbitrary image texture node?

You can use BlendDataImages.load() to load and assign the image to the texture node in one go. Following demo is based on Control Cycles material nodes and material properties.

Make sure there is a material assigned to the object in context and the file path is correct:

import bpy

Get the active material of the object in context


mat = bpy.context.object.active_material


Get the nodes


nodes = mat.node_tree.nodes
nodes.clear()


Add the Principled Shader node


node_principled = nodes.new(type='ShaderNodeBsdfPrincipled')
node_principled.location = 0,0


Add the Image Texture node


node_tex = nodes.new('ShaderNodeTexImage')


Assign the image


node_tex.image = bpy.data.images.load("//your_image.exr")
node_tex.location = -400,0


Add the Output node


node_output = nodes.new(type='ShaderNodeOutputMaterial')

node_output.location = 400,0


Link all nodes


links = mat.node_tree.links
link = links.new(node_tex.outputs["Color"], node_principled.inputs["Base Color"])
link = links.new(node_principled.outputs["BSDF"], node_output.inputs["Surface"])

In case you'd like to use an image that has been loaded or even is packed already, you can get it via image data-block and assign that reference to ShaderNodeTexImage.image:

...

Add the Image Texture node


node_tex = nodes.new('ShaderNodeTexImage')
node_tex.location = -400,0


Get the image and assign it to the Node.image


img = bpy.data.images.get("Image Name")
if img:
    node_tex.image = img


...
