Magnificent, thank you for this! This did work and I was able to find the respective selectors to adjust throughout the page. (After consideration I was looking for text first then image, so just the matter of selecting those rows for column-reverse instead)
 
Thanks again!

Thank you so much, it worked!! 

I believe that might be the same thing I am experiencing as the page I detailed where this works is an instance of image galleries and text whereas the new page I noted where the code is not working is individual image blocks with text blocks as you have too. 
I haven't received a reply on the thread I made, but if a solution shows up there, I'll come back here to update as well!
