Update example content to be accessible.

Description

We must go through all the example content and make sure that it meets WCAG guidelines. This includes:
1. Checking color contrast for text with transparent background
2. Images have a good text describing what the image is "telling" the user. (Not like "Just another flower", "Strawberry" etc. – must be seen in context of the task – why is the image there)
3. Must be readspeaker accessible and have the proper labels.

Acceptance Criteria

Bullet points 1. 2. 3. are "met" for all example content.
