I will recommend PMwiki. It's easy to learn even if you have little
previous experience with managing websites, and is very flexible and

I don't see why they shouldn't be. Read trough them quickly and there
are no significant basic changes to pmwiki (just new features).

The solution suggested in the old threads is to do a string replace of
wiki syntax for each page.This might help:

With the GUIeditbuttons of PMwiki it should be rather easy for you to
get used to the new syntax.

As you probably noticed uploading pictures to pmwiki is handled by the
attach-markup, so uploading new pictures is not difficult. I suppose
that you can move all the files into a uploads directory and convert the
image links into pmwiki-markup.

As for thumbnails there is a recipe here:
I haven't tried it myself, but it seems like it works for some people at

Instead of having someone creating a custom wiki for you, have that
someone help you do the conversion, it's probably easier and cheaper.
Maybe try to ask some of the people that did a succesful conversion
before (seems like Oliver Betz is both active on this list and have
converted from phpwiki earlier).
