[Fixed]-Sorl-thumbnail: Creating a thumbnail inside a for loop in a template

It looks like your plural are in the wrong spot:

{% for post_images in post.sellpostimage_set.all %}

should be:

{% for post_image in post.sellpostimage_set.all %}

post_image = SellPostImage.objects.filter(post=poster_posts)
context_dict['post_image'] = post_image

should be:

post_images = SellPostImage.objects.filter(post=poster_posts)
context_dict['post_images'] = post_images

or:

post_image = SellPostImage.objects.get(post=poster_posts)
context_dict['post_image'] = post_image

why do you do this in your template:

{% for post_images in post.sellpostimage_set.all %}

if you have post_images in the context?

How does this work?

<img class="thumbnail" src="{{ post_images.pictures.url }}" />

shouldn’t it be:

<img class="thumbnail" src="{{ post_image.picture.url }}" />
