Hi again Don,


Oh ok, if you're not worried about it that's fine.  Just thought
if there was picture files mixed with other types of files (like
maybe text files) you may not like the results due to the way
'count' looks like it is being handled.  If you are always viewing
directories that always contain only supported file types then
there wont be a problem, but if there is even one unsupported type
the count may get messed up.
I found this by accident :) when the ex.err file ended up in the
same dir as my trial pics.  I was wondering when i went through
all the files the pic numbering wasnt the same when i got back down
to "1 of 8".  "1" had become a different pic :)
I was still able to view all the pics however so that was good.



Take care,
Al

And, good luck with your Euphoria programming!
