I am a little puzzled. I wanted to change the fixed logo & thumbnail to something that can be updated more easily, loading from a gallery. And although the documentation of Look & Feel says images can be loaded via standard TikiWiki syntax, my attempts have failed to load an Image either from the image gallery or the file gallery, so both
img id=15 and fileId=14 in proper brackets failed. Any tips?
Not sure about Tiki18.3, on Tiki20 it work with "display15".
If not try "dl15&display" or "dl15&preview" (not sure which one should work).
