i worked with picasa and simpleviewer before, and had no problem with them.
However, i guess after i updated my picasa, picasa no longer be able to cope with simpleviewers' templates.
so i downloaded the simpleviewers' templates properly like what i did before, and when i go to the picasa drop down menu to export my album,.. there is no templates from simpleviewers are shown... except the ones from other companies....

i am not sure if this happen to other people too.
