so i strongly suggest, urge and beg you to install such a feature.  i
can see how it would be near impossible to track pictures sent out of
picasa itself, since those can go out through various e-mail
programs.

but picasa web only goes out through gmail, so how about it, y'all.

i hate it when people point to what their old or other program used to
do -- i always think, "well, if your old program was so great, why
didn't you stay there".... i'm sure they  had good reason to switch,
or add this, but miss old features.  as do i.  but this is here and
now, so i want to learn to use picasa and picasa web and become
proficient with it.

EVEN SO, photoshow print & share, did have that feature.  with my
memory, these days, that component is real important.   but psps is
not compatible with vista.  (vista isn't compatible with a lot of
things.  boo, hiss, and i'll remember never to get the first
generation of anything again.)

that's my $.04,  chanita
