    Unfortunately, it's currently not possible to control the max upload size in the mentioned widget. As for the image file extension, I think the widget allows the majority of the extension such as the JPG, JPEG and PNG.

    I have requested this to our widget team. We'll let you know through this thread if there updates on that.

    Hi Welvin,

    if I try to upload e.g. a 25M-file, I always get the following message: There was an error uploading, try

    to re-upload it 


    An 7M-file works without any prblems. Which is the allowed max. filesize for this widget?

    Best regards, Oliver

    18MB works for me. I will have to ask this to our widget team and let you know here for the max file size.
