You can change a Google Drive image link to a download link by swapping for (just use a replace all tool, I'm fond of TextMechanic's simple, free, online Find and Replace but Notepad find and replace will do the trick).
I'm a user of Google Drive and as you say it's just a matter of getting the download link. An example on my drive is
https://drive.google.com/file/d/0Bz697J8sF_ekS1ZSV0tGSS1ZbHc/edit?usp=sharing
for the share link, or
https://docs.google.com/file/d/0Bz697J8sF_ekS1ZSV0tGSS1ZbHc/edit
for the edit link. The download link is
https://drive.google.com/uc?export=download&id=0Bz697J8sF_ekS1ZSV0tGSS1ZbHc
as described in this article.
So it's simply a matter of find and replace on
https://docs.google.com/file/d/
or https://drive.google.com/file/d/
for https://drive.google.com/uc?export=download&id=
and finding and replacing /edit
or /edit?usp=sharing
with
(nothing i.e. deleting them)
Once you've done that you can download a list of files in a number of ways, but if you want to stay in the browser I've written a Chrome extension called TabSave to do just that - there's an option to use a manual list for downloading (it also allows downloading files in every tab of a window).
You can just paste in from your list of edited URLs and they'll download. Very lightweight and you don't need to worry about dodgy installation of these one-hit wonder freeware programs. All the code is open source on GitHub (link in the webstore description).

? Can you explain that part about converting links? I don't get that. What do you mean by that? Your file ID would normally sit after the&id=
. Obviously you have removed it here for privacy. But are you saying you can't paste that URL in your browser and hit Enter to display it? Are you getting a 404 status error or something of that nature? You have to explain better what you're trying to do and how you're trying to do it.
