That is a lil more complicated, you will need an online Photo Shop and a storage site to store your images. Will look forward to your future creations.
You are making it too complicated.
Just find pictures and save them to a file on your computer.
Edit (add text) the pictures in MS Paint, a basic easy to use photo editor on all computers using windows.
Then you can upload the meme from your computer to https://postimages.org/ for an URL that you can use to post on this forum.
I must be old school, figures that the process has been simplified. Thanks for the info.
