template:`

{% category in items %}                 <div class="col-sm-4 col-lg-4 col-md-4">                     <div class="thumbnail">                         <img src="{{ category.picture }}" />                         <div class="caption">                             <h4 class="pull-right">${{ category.price }}</h4>                              <h4><a href="#">{{ category.itemname }}</a>                              </h4>                         </div>                      </div>                 </div> {% endfor %} 

models.py:

from django.db import models  class storecategory(models.model):     categoryname = models.charfield(max_length=128)     def __unicode__(self):             return self.categoryname  class storeitem(models.model):      category = models.foreignkey(storecategory)     itemname = models.charfield(max_length=128)     description = models.charfield(max_length=1024)     price = models.decimalfield(max_digits=16,decimal_places=2)     quantity = models.integerfield(default=0)     picture = models.imagefield(upload_to='store_images', blank=false)     def __unicode__(self):             return  self.itemname 

urls.py:

urlpatterns = patterns('', url(r'^$', views.webstore, name='webstore'), url(r'^fiberarts/$', views.fiberarts, name='fiberarts'), url(r'^fiberarts/(?p<directory>[\w]+)/(?p<image_name>[\w]+)$',views.getimage) ) 

view: ( never called, problem regex?)

def getimage(request, directory, image_name):     imagelocation = directory + '/' + image_name     print imagelocation     image_data = open(imagelocation, "rb").read()      return httpresponse(image_data, mimetype="image/png") 

edit: here error i'm getting:

[06/apr/2014 15:48:35] "get /webstore/fiberarts/store_images/product_150_1.jpg http/1.1" 404 3743 

change url regex (?p<directory>[\w]+)/(?p<image_name>[\w]+\.[\w]+)$' , fix view accept right number of arguments. should receive right image_name inside view.
