you should upload them in hthe HTML module (there is an upload button)
then they are accessible under : modules/html/ + ID where id is what you have given for id.
for instance modules/html/a/b/c.gif is you have uploaded the file under a/b/c.gif
Thank you for the clarification, after reading your post I realized I was using the real file name, instead of the file id - which I made different in my first test case.
So I gather from your response I can also include /'s in the file id to resolve name conflicts, ah yes, I just tested it - works as advertised.
So for pages with numerous images, is there a backend way to load a large grouping, without manually clicking through each upload?
yes there are import/export facility, look at the source code of the html module.
it need to be redone, the flat view is quickly overloaded.
Hmm, I seem to be overlooking what you're talking about. I don't see anything in regards to batch importing an entire grouping of files.
Thanks for your patience,
the operation are backup/restore :
they are pretty undocumented but here.
