getUrl using my original develpment server domain I have the following code and after moving site to a live server, the img src is using the old domain, however, the anchor links have correct domain name.  Any idea what the issue is?

                                {% for block in entry.threeHomepageImages.type('images') %}
                                    &lt;div class="col"&gt;
                                        &lt;div class="image-block"&gt;
                                            &lt;div class="image"&gt;
                                                {% if block.image|length %}
                                                    &lt;a href="{{ block.pageLink.first().getUrl() }}"&gt;&lt;img src="{{ block.image.first.getUrl() }}" alt="{{ block.alt }}"&gt;&lt;/a&gt;
                                                {% endif %}
                                            &lt;/div&gt;
                                        &lt;/div&gt;
                                        &lt;h1&gt;&lt;a href="{{ block.pageLink.first().getUrl() }}"&gt;{{ block.imageTitle }}&lt;/a&gt;&lt;/h1&gt;
                                    &lt;/div&gt;
                                {% endfor %}
Have you checked the path of the asset source the image is in? Sounds like that might still be the old server's path.
Best practice is to use Environment-specific variables in your config file, and then use those in you Asset Source settings as well.

So, use {basePath}assets/site as your File System Path for instance (if you've used basePath as a config variable). 

That way, it will adapt to whatever environment you're working on.
