Need alittle hlpl with an image scraper.

[wavic]

So, as I can see mechanize is used just to retrieve the web page. If the page is not build with JavaScript you don't need mechanize. Use requests module instead. 
Or replace mechanize with selenium

Also, you never call grab_my_pictures() function. I don't see where requests.get(final_link) gets the web address from either.

Are you sure this is the full script?
