how to check image size before download

I have image at url as below:

http://ipcamera-viewer.com/image/?p=199619_20170221_162149_7208.jpg

Because I can't download it easily so I used way like this

browser.get(urlServer)
browser.save_screenshot(pathLocal)

I don't want to download image only black that size is small, so I want to check the file size, I tried to use 

imgData = browser.get_get_screenshot_as_base64()
if len(imgData) > 5000: browser.save_screenshot(pathLocal)

But base64 is not the same as image size, what can I do?

This question may provide some insight. It says to multiply by .75 to get an estimated result of the size of the image in bytes which you can compare to. 

if (len(imgData)*.75) > desiredBytes: browser.save_screenshot(pathLocal)
