I run several blogs by visual-artists and web-designers who want a quick way to insert images into their blog without the awkwardness of WSYIWYG and without the technicality of code (eww...).

Thanks in advance for your input.

#Syntax in a blog goes:
[[thumb:the-image-slug]] # Gives you a thumbnail
[[image:the-image-slug]] # Presents full-size-image

Then of course:

{% blog.post|yeagowiki %}

You will also need to create some templates (see snippet). Here's a sample:

<!-- /templates/photologue/image_snippet.html -->
<div class="photologue-image">
    <a href="{% if url %}{{ url }}{% else %}/media/{{ image.image }}{% endif %}">
         <img src="{{ image.get_display_url }}" />
    </a>
    <p class="photologue-image-caption">{{ image.caption }}</p>
</div>
