``` In [3]: from PIL import features ...: print (features.check_module('webp')) True ```

@vstoykov I am trying to upload this file ``` class Image(models.Model): file = models.ImageField(upload_to='images') preview = ImageSpecField(source='file', processors=[ResizeToFit(150, 150)], format='WEBP', options={'quality': 80}) def __str__(self): return '/' + self.file.url class Meta:...

Please notice I cannot upload previews to imgur or on github directly. Sites give errors that they do not support this file format.

@asvetlov thank you!

> Have you tried playing with the buffer_size option in the axelrc file? No. @sdt thanks for help!

I set but it still change file every second. ``` cat ~/.axelrc num_connections = 10 buffer_size = 512000000 ```

I want help, but I can not understand how it works. It is looks like it send one request per second to http://127.0.0.1:9000/_debugtoolbar/sse?request_id=313339383833313133303438313638 and get the same data every time.
