img = driver.find_elements_by_css_selector('.gem-gallery-thumbs-carousel img')
for i in img:
    y = i.get_attribute('href')
    print(y)

result:     
None
None
None
None
None
None

Answer 1

1. The image urls in those elements are contained in src attribute, not in href as mentioned in comments.
2. You probably should add wait / delay to make the page loaded before reading the elements contents.
   So, something like this After appropriate wait / delay should work:

imgs = driver.find_elements_by_css_selector('.gem-gallery-thumbs-carousel img')
for img in imgs:
    url = img.get_attribute('src')
    print(url)

Answer 2

To output the srcs for those you need to.get_attribute() for src

wait=WebDriverWait(driver, 60)
driver.get('https://ca.morilee.com/product/quinceanera-dresses/vizcaya/iridescent-crystal-beaded-quinceanera-dress/')
imgs=wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR,".gem-gallery-thumbs-carousel img")))
for img in imgs:
    print(img.get_attribute("src")

Imports:

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC
