The summary page of some studies loads very long

Every screenshot will be loaded in its original resolution, when the summary page is loaded. This can take very much time. For example for this page.

1st we should remove all report images from test study 1. I assume this is a manual process?
2nd we should change image format of screenshots from PNG to JPEG.

I will do this

All report images from study 1 are removed. But I haven't removed the unused image files from the csis directory, yet.

2nd we should change image format of screenshots from PNG to JPEG.

JPEG images are now used

Unused files will be deleted from the file system, if the status of the file is temporary (table file_managed, field status = 0) and the last change was 3 month ago (this can be changed here).
But the current drupal version does not change the status of orphaned files to temporary. (See here)

The status can be set manually via the database. For example with an update statement like this

update file_managed set status = 0 where fid in ( select m.fid from file_managed m left join file_usage u on (m.fid = u.fid) where coalesce(u.count, 0) = 0 )

To delete the files now instead of after three months, the database fields "created" and "changed" should be changed.

All files, which are temporary and the last change was 3 month ago, will be deleted during the drupal cron job (The drupal cron job can be configured here). Note: one run of the drupal cron job removes a maximum of 100 files.
