Dear all,

I am using Odoo v12 and everytime I start my development server I can see several lines with the messages like:

2019-07-03 10:11:21,011 11856 INFO dbname werkzeug: 127.0.0.1 - - [03/Jul/2019 10:11:21] "GET /web/image?model=&field=image1&id=2782&unique= HTTP/1.1" 304 - 17 0.016 0.049

That's about 20 lines with this type of image.

Can anyone tell me what are this messages related to?

Thank you all in advance

Best regards
