Renaming an image created in Dalle so it has a unique file name before inputting into wordpress

I am creating an image with Dalle but it names it file.png everytime, so this works once, then when the scenario runs again, it just overwrites the file, how can I create a unique file name for this so once it posts to wordpress it has a unique file name and does not use the file.png everytime?

I tried using HTTP get a file then using a separate HTTP module get a file after to get that file and rename it but it does not seem to be working.

Your on the right track. Use the HTTP module Get a File and then upload it somewhere like Google Drive. It also lets you rename it at the same time.
