MemoryError: memory allocation failed, allocation x bytes - i2c

Question

I'm trying to code a program that loops a short gif of a sun on a 1306 oled using a raspberry pi pico. I am copying the code from a tutorial I'm using and I'm getting this error when running my code.
from machine import Pin, I2C
from ssd1306 import SSD1306_I2C
import framebuf
import time
WIDTH = 128
HEIGHT = 64
i2c = I2C(0, scl = Pin(1), sda = Pin(0), freq=400000)
display = SSD1306_I2C(WIDTH, HEIGHT, i2c)
images = []
for n in range(1, 28):
with open('/TEMP/image%s.pbm' % n, 'rb') as f: #open folder and image
f.readline() # Magic number
f.readline() # Creator comment
f.readline() # Dimensions
data = bytearra y(f.read())
fbuf = framebuf.FrameBuffer(data, 64, 64, framebuf.MONO_HLSB) #adjust accordingly the width and height
images.append(fbuf)
while True:
for i in images:
display.blit(i, 32, 0)
display.show()
time.sleep(0.01)
then I receive this error:
Traceback (most recent call last):
File "<stdin>", line 19, in <module>
MemoryError: memory allocation failed, allocating 5000 bytes

Your device does not have enough memory to fill all images into RAM. Read each image and show it on screen one-by-one
from machine import Pin, I2C
from ssd1306 import SSD1306_I2C
import framebuf
import time
WIDTH = 128
HEIGHT = 64
i2c = I2C(0, scl = Pin(1), sda = Pin(0), freq=400000)
display = SSD1306_I2C(WIDTH, HEIGHT, i2c)
images = []
while True:
for n in range(1, 28):
with open('/TEMP/image%s.pbm' % n, 'rb') as f: #open folder and image
f.readline() # Magic number
f.readline() # Creator comment
f.readline() # Dimensions
data = bytearray(f.read()) # there was space, probably typo posting your question
fbuf = framebuf.FrameBuffer(data, 64, 64, framebuf.MONO_HLSB) #adjust accordingly the width and height
display.blit(fbuf, 32, 0)
display.show()
time.sleep(0.01)
