If I post an image and use a google sheet to record the URL, then replace the image, the URL changes, so I would recommend instead that you should try to find a location online that you can post and repost images to, then use that URL to upload into glide as that link will not change.
Thanks for your responses - it seems it is not possible as @Darren_Murphy has gotten informed by Mark.
To clarify, I want to post/upload an image into Glide via API - a bit like using image picker by a person. In that way the url will be something like this:
Yeah, I had some cases for this but I asked it in the experts chat a while ago and it’s not possible. I process some files via email and they must be uploaded somewhere to be shown in Glide. It would be ideal if that “upload image” action is available via API, but currently I have to upload to Google Drive instead.
