maxymama asked in her journal how to set up a header, and outlander hinted that it would make a good post for this community.
So I'll just try and give the explanation a shot with my profound half-knowledge.

Beware: the following instructions are from the perspective of a free account user. But there are probably one or two things that will work the same in paid accounts.

( More behind the cut )

I need some help. I would like to put an header or an banner in my profile. But I can't get it work.
And all the explanations I found somewhere in IJ sound like an alien language to me. So please keep it plain and simple as possible.
What have I to do??

Thanks and kisses ♥
Michi




ETA: Thanks of the help from happier_bunny, it works!!
