Using the Jekyll collections API, which, as of 2015-08-07 came with the big warning

Collections support is unstable and may change

Files in collections that do not have front matter are treated as static files and simply copied to their output location without processing.

Static files have the following attributes:

• file.extname

And then the code on your page would be something like (untested):

{% for image in site.images %}
     {% if image.extname == 'jpg' %}
         
     {% endif %}
{% endfor %}
