You can also use "Tell us" or "Tell me" instead of "Say" or "Speak."

All four sentences are grammatically correct. However, there are some slight differences in meaning and usage.

1. "Say your thoughts about the following." This sentence implies that you are asking for someone's personal thoughts or opinions on a specific topic or issue. It can be used in a more formal or professional context.

2. "Say your ideas about the following." This sentence suggests that you are requesting someone's ideas, suggestions, or proposals regarding a particular topic or problem. It is similar to the previous sentence but places more emphasis on generating creative or innovative solutions.

3. "Say something about the following pictures in your own words." This sentence is asking for a verbal description, interpretation, or commentary on a set of pictures. It allows for an open-ended response, where the speaker can express their thoughts, emotions, or observations.

4. "Speak your own ideas about the following." This sentence is quite similar to the second one and is also requesting someone's personal ideas or opinions about a specific topic or issue. It can be used in a more casual or informal setting.

In summary, all four sentences are grammatical, and the choice between them depends on the specific context and the information you are seeking.
