Is there any tiddly react when external file is not founded ?

[Marc Viot]

Hello,

I would like to use external file on google drive or dropbox to view image or pdf. But I don't know if user can access to them  because he needs to be online. So I would like to test if external file are or not. Is there any message to test ?

Thank's a lot

It is not clear what you mean. Is the "external file" the TW or the image?

Again unclear, at least to me.
