Descriptive alt texts on images are important, but in TinyMCE the field is called «Image Description». You can change that!
MediaData, the base class for files and images in Episerver, does not implement ILocalizable and thus does not have the option to include culture-specific properties. I present a workaround.
The texts in the Episerver UI can sometimes be confusing for the editors. Luckily, we can override all texts stored in Episervers language files, in two easy steps.
See how to replace the language code in the Episerver page tree with the full language name.
