Import and Link image texture to an Active Shader Node in Python

Question

I'm working on a part of an Addon that create a New Principled BSDF shader then a ShaderNodeTexImage (make it active), import an image with File brother and link it to the ShaderNodeTexImage.

Everything works except for the last step link it to the ShaderNodeTexImage Texture_Node.image = ('img.name')

How can I tell blender get the name of the last image imported?

I've tried to create Lists before and after importing image and compare them to reach the new picture imported, but the command Texture_Node.image expect a string not a list or a set. and O'm sure there is a better way to reach the name of the last picture imported.

import bpy


material_bascic = bpy.data.materials.new(name= "New Mat")
material_bascic.use_nodes = True

bpy.context.object.active_material = material_bascic

principled_node = material_bascic.node_tree.nodes.get('Principled BSDF')

Texture_Node = material_bascic.node_tree.nodes.new('ShaderNodeTexImage')
Texture_Node.location = (-300,215)

material_bascic.node_tree.links.new(Texture_Node.outputs[0],principled_node.inputs[0])

nodes = material_bascic.node_tree.nodes
for node in nodes:
    node.select = False
    
Texture_Node.select = True
nodes.active = Texture_Node

bpy.ops.image.open('INVOKE_DEFAULT')

#Texture_Node.image = img

The usual technique for finding the last thing created by a bpy op works here. In this case you want bpy.data.images[-1].

This works because bpy ops that create things usually add them as the last item on the bpy.data structure that's relevant, in this case, the image structure and [-1] is a Python idiom for finding the last element.

import bpy


material_bascic = bpy.data.materials.new(name= "New Mat")
material_bascic.use_nodes = True

bpy.context.object.active_material = material_bascic

principled_node = material_bascic.node_tree.nodes.get('Principled BSDF')

Texture_Node = material_bascic.node_tree.nodes.new('ShaderNodeTexImage')
Texture_Node.location = (-300,215)

material_bascic.node_tree.links.new(Texture_Node.outputs[0],principled_node.inputs[0])

nodes = material_bascic.node_tree.nodes
for node in nodes:
    node.select = False
    
Texture_Node.select = True
nodes.active = Texture_Node

bpy.ops.image.open('INVOKE_DEFAULT')

Texture_Node.image = bpy.data.images[-1]
