Looks like I'm getting an IOerror in the create_thumbnail() function in models.py

I had to add a print statement to be sure. It doesn't alert the user in any way when it happens. just returns.
except IOError:
print('IOError')
return # What should we do here? Render a "sorry, didn't work" img?

I'll update after more testing.

OK. Figured it out.
Things have changed a bit in recent versions of Pillow.

Therefore, if you try to upload a png and AVATAR_THUMB_FORMAT is set to 'JPEG', the image upload will fail silently with an IOError: cannot write mode RGBA as JPEG

If the AVATAR_THUMB_FORMAT is set to 'PNG' everythings fine.

Here is a link to the Pillow issue that helped me out with this. python-pillow/Pillow#2609

The alpha channel must first be removed to save the png as jpeg like so:
image = image.convert("RGB")

The create_thumbnail() function in models.py will need to be edited to fix this

Does that mean I have to decide if my users should upload jpg or png images? That would be inconvenient. I'm experiencing the same issues. But I'm generally using jpg - and the pngs are not created.

I'm running django-avatar 4.1.0

Any update on this? Are we forced to make users choose one type of image format out of the box? Experiencing the same issue with 4.1.0

@Lone1567 I think we're just waiting for a PR on this one.

submitted PR #180

I just encountered this problem too.

Also encountered this issue. AVATAR_THUMB_FORMAT = "PNG" fixed the issue

This project seems to be quite low on maintenance, with last merge being on 2020.
I wonder if it would be a candidate for https://github.com/jazzband , since other great Django projects are also harboured there.
