When to put an Image in a figure or a paragraph?

Question

I dont really get the difference. When should I put my Image in a paragraph and when should I put it in a figure?

Answer 1

When it's more appropriate regarding the context :P

But why to choose between <figure> or <p>?
The semantical logic could be:

<p>
<figure style="float:right"><img src="img_url" alt="description"></figure>
My text to wrap my figure-image...
</p>

Difference could only be in semantical meaning and visual aspect. But the last is... secondary, as we can style any element as we need/want ^^
