When uploading one or more images as sub-items through the DropAreaComponent, the alternative text for the image is set to the filename. Github link to the lines of code where this is done.

This does not happen when uploading images other places. This seems to me like a bug or oversight.

It's quite useful to set alternative text automatically, but the default should probably not be the filename. This means that users who are uploading images this way not only have to find the correct alternative text to use for the image, they also have to empty the field before typing a description of the image.

There are several possibilities here. It could be possible to read information from the exif data of the image, let the user edit the alternative texts for all images in the DropAreaComponent just after the images have been uploaded, or maybe something else.
