Background of the issue:
I have an issue with the media photo - it's assigned in media translation however I don't see the translation in the English version: hidden link
Symptoms:
The translated media photo does not appear in the English version of the site.
Questions:
Why is the translated media photo not appearing in the English version of the site?
2. The issue on the frontend (no images) was due to the fact that you added the image as a background but the slide doesn't have any content. Moving the image inside the content resolved the issue.
3. When translating your page you will need to search for "http" in order to see links such as image links and translate them manually.
PS: I didn't remove the test page so you can test it yourself before updating your pages.
