File:Everybody's Fool (Evanescence single - cover art).jpg is 471 × 415 pixels

in littleimage.py, routine gimme_image and about 24 lines down, it works out the size... (print statements are mine)

		img = Image.open(item10)
		print "img.size[0]", img.size[0]
		print "img.size[1]", img.size[1]
		basewidth = int(math.sqrt((pxl * float(img.size[0]))/(img.size[1])))
		print "basewidth",basewidth
		wpercent = (basewidth/float(img.size[0]))
		print "wpercent",wpercent
		hsize = int((float(img.size[1])*float(wpercent)))
		print "hsize",hsize
		
		original_pixel = img.size[0] * img.size[1]
		print "original_pixel",original_pixel
		modified_pixel = basewidth * hsize
		print "modified_pixel",modified_pixel
		pct_chg = 100.0 *  (original_pixel - modified_pixel) / float(original_pixel)
		print "pct_chg",pct_chg
		if pct_chg > 5:
			png_info = img.info
			img = img.resize((int(basewidth),int(hsize)), Image.ANTIALIAS)
			img.save(filename + extension, **png_info)
		else:
			print "Looks like we'd have a less than 5% change in pixel counts. Skipping."
			results = "PIXEL"
			return results

The result of the prints are below

img.size[0] 336
img.size[1] 296
basewidth 336
wpercent 1.0
hsize 296
original_pixel 99456
modified_pixel 99456
pct_chg 0.0
Looks like we'd have a less than 5% change in pixel counts. Skipping.
Removing tag...already reduced...

So a picture of 471 × 415 pixels is being decoded as 336 x 296 pixels. Either the calls are wrong or this is a BAD file - it's old enough to be in the area where I seem to recall there was a massive image problem. The bot may be OK, the image might be at fault.
