Hi Hugo,
That file is stored in the database in a varbinary(max) column, so there should fit ~ 2gb of data for that background image.
Can you share the image? Do you get any error while uploading? Do you have a failed request or something similar?
Kind regards,
Tim de Lang
@Hugo Nienhuis This issue might also be caused by the Azure WAF, see Azure setup | Thinkwise Documentation > Request body length exceeded the limit
I get following error when uploading the image:


It looks like Arie may be right about this. I will try to see if I can have the WAF setup changed.
Hi @Hugo Nienhuis,
Did you manage to get this working?
Yes, changing the WAF settings worked.
