Problem with failed login for upload/export to piwigo - solved

[Gilles Caulier]

Hi,

Thanks for this report.

I recommend to add an entry with your feedback to the bugzilla section,
where the original Piwigo tool developer is in CC by default. Like this we
have a safe trace of your feedback, and he can comment properly this tip.

Look here :

> 4. Click 'The whole set' to select all the orphan photos

> Exporter logs in to PWG and queries for albums to populate the list in the

> When you click Upload, the exporter asks PWG how many pictures it has - PWG
> replies with the total number of images it has including orphaned images
> Then the exporter checks the status of the last image (from the total
