Hello,
I have a multi language website. The client needs to add some Media metadata used in captions over the images. This needs to be defined once and reused in different places on the website. That’s why I decided to extend the Media Type Image and add some text fields to it, so when the editor creates the image also adds this data. My problem is that this data needs to be language specific and I don’t see anyway to enable Vary By Culture on Media Type Image. I assume it’s not supported (yet)?
But if so, could you give me some ideas on how to accomplish that without having to complicate the editorial process adding some other Document type which will contain an image field and the other text data which can vary by culture in that scenario. I was thinking maybe to connect the Media Type Image somehow with Dictionary values under Translation tab but it should be also editorial friendly
