✅

You have duplicate M2M with Tag as albums you my want to change that for Album. Also good idea to have related name as well

tags = models.ManyToManyField(Tag, blank=True)
albums = models.ManyToManyField(Tag, blank = True,)

change to

tags = models.ManyToManyField(Tag, blank=True, related_name="img_tags")
albums = models.ManyToManyField(Album, blank = True, related_name="img_albums")

When you have two fields that are foreign keys to the same model, you need to provide a related_name so django knows what to call the relation. That’s what the error is saying.

So, update your model by giving your relations a unique name:

tags = models.ManyToManyField(Tag, blank=True, related_name='image_tags')
albums = models.ManyToManyField(Tag, blank = True, related_name='album_tags')

However, what you probably meant is this:

tags = models.ManyToManyField(Tag, blank=True)
albums = models.ManyToManyField(Album, blank=True)
