#input your search item here
searchterm = 'Tomato'
url = "https://www.google.co.in/search?q="+searchterm+"&source=lnms&tbm=isch"

#insert path to chromedriver inside parentheses
browser = webdriver.Chrome()
browser.get(url)
img_count = 0
extensions = { "jpg", "jpeg", "png", "gif" }
if not os.path.exists(searchterm):
    os.mkdir(searchterm)

for _ in range(500):
    browser.execute_script("window.scrollBy(0,10000)")
    
html = browser.page_source.split('["')
imges = []
for i in html:
    if i.startswith('http') and "https://encrypted" not in i:
        if "https://i.ytimg"  not in i:
            imges.append(i.split('"')[0])
            wget.download(i.split('"')[0], "#download path")
