I've got a file with hundreds ready to go, both memes and gifs and I've almost done it myself !
I know this might seem sad, but I have recorded everything I have ever posted in an Excel spreadsheet so I can avoid this. :~)
I started the Spreadsheet with a week or two of starting and just add to and update every day.
It looks to me you have a full time job on imgflip but I feel there is nothing better than doing something you love :~)
