This may not be the best place to ask, but I've tried multiple other resources, and my searches have led me here.
I am trying to create a link that, once posted to Twitter (or another site) randomly generates an image from a specific list of images saved to my computer (or uploaded to the site). The tool would produce a new random image upon the page being refreshed.
I know that this is possible for other sites, because back in the day (2009ish), I used an online tool to generate a random banner for my guild on GaiaOnline. The site that I used (undev dot org, with the help of Tinypic) no longer exists, and I cannot, for the life of me, find something similar. It probably exists, but I can't figure out what to google to find it.
Someone recently suggested I search for a "dynamic header" for Twitter, but it's not a header that I want. I want to be able to put the link in a post on Twitter, and then every time that the post is refreshed, a different image appears in the post.
Does anyone know of a site that will allow me to accomplish this? Is there something else I should try searching google for? If not, is there another way that I can achieve this goal? I'm new to programming (C++ and a little bit of Python), and I'm not sure what else I would need to learn or learn about in order to achieve this. Thank you.
What you are looking for is Twitter Cards (the snippets that appear on Twitter when you paste a link), however, they are cached for 7 days so there is no way to do this with dynamically updating images.
