I got this "working" at the end.
Instead of trying to get BC to do this "alone", I instead have a server running, which uploads the images to the BC
site via SFTP, so the reference to the picture is on the server. Now i can edit the picture in size, shape etc. in the summernote editor,
and then publish it
You can save base64 no problem now in the BC Apps (admin area only) but not on the front end (yet).
Nice to know, maybe I can use it later on.
Hope it is coming to the front end, even though I solved this in another way, but outside of BC,
it might be helpful further on.
Other thing to remember is data fields and their character limits. One base64 image will burn through that in a flash and be truncated.
He wants to store it as a file not in a webapp database, you can save a base64 file to a binary file no problems.
of course, but of any case someone via say front end tries to store base64 image data say in a multiline etc (of which there have been several) they wiill have incomplete image data because of the character limots.
