base64 issue ?

[Emodroid]

Hello, i'm facing an issue since 3 days without change anything.
I'm actualy use the plugin v2.2.3 and since 3 days when i try the upload an image on my medium edition the picture is in base64 instead an image src url.

If i try the update the plugin version to the latest (v2.5.1) i have an error in the console (Uncaught TypeError: this.getEditor(...).trigger is not a function) and the picture is a blob. The upload function doesn't work.

If i can keep my old version, is it possible to force the plugin to use an image src url instead of the base64. If not, how to fix the v2.5.1.

Thank you very much for your help.
