'640' is not a valid size.

Steps to reproduce

Expected behaviour

1.Link is opening 2.Image is provided

Actual behaviour

So, I've tried to install this app, and at the first glance everything works pretty fine, but when I'm trying to add a picture I get this error.

This exception is shown because in my settings I set easy-thumbnails debug option to True(link)

Additional information

What I did to fix it is changed BLOG_IMAGE_FULL_SIZE size from 640 to 640x640 in djangocms-blog/settings.py and it worked.

when there is no BLOG_IMAGE_FULL_SIZE in the settings, the picture also does not appear.

I just had this same problem: if you don't provide a width AND a height in your settings, the image will not be loaded (the src attribute is empty). It can be fixed with a custom setting like this BLOG_IMAGE_FULL_SIZE = {"size": "640x640", "crop": True, "upscale": False}, but it would be nice if the image would be rendered without specifying the width and height with an HTML attribute. It's hard to deal in responsive designs with it.

I just stumbled upon this as well - it would lovely to have this in the installation instructions, if nothing else.
