[Feature Request]: No Image data blocks found

[ema7569]

What would your feature do ?

On launch the web verify things and say this cryptic message: No Image data blocks found
I think it's because one extension has a missing image.preview or another thing, but it is possible to be more precise on this error message? Like also giving the extension name, the file path or any other info why this message show?
Thank

Textual inversion embeddings can be embedded in a PNG file, like this.

It checks each PNG file in the embeddings folder and displays this message if it's just a normal image.

	data = extract_image_data_embed(embed_image)
	if data:
	name = data.get('name', name)
	else:
	# if data is None, means this is not an embedding, just a preview image
	return

Lines 112 to 118 in adadb4e

	def extract_image_data_embed(image):
	d = 3
	outarr = crop_black(np.array(image.convert('RGB').getdata()).reshape(image.size[1], image.size[0], d).astype(np.uint8)) & 0x0F
	black_cols = np.where(np.sum(outarr, axis=(0, 2)) == 0)
	if black_cols[0].shape[0] < 2:
	print('No Image data blocks found.')
	return None

Images ending in .preview (e.g., embedding.preview.png) are ignored, as are other formats, such as JPEG.

	if ext in ['.PNG', '.WEBP', '.JXL', '.AVIF']:
	_, second_ext = os.path.splitext(name)
	if second_ext.upper() == '.PREVIEW':
	return

TLDR: It's harmless; you can ignore it.
