@K.MuratI understand why these thumbnails are needed but what I truly doubt is:
2. You can select to backup your catalog with or without thumbnails. Because thumbnails are something that could be regenerated later, from actual files;-K.Murat
Is it really always necessary? Couldn't Daminion check if this is needed on assumption of file size?
My exact case was:
I have 2881 SVG files which are mainly icons. Since there is no image organizer for vector files, I had decided to make mirrored directory with PNG versions of them. Simple batch script for rsvg-convert.exe did the work and I have few thousands thumbnails - 512 pixels wide. From my point of view it is now not worth it to have Daminion to offer thumbnails of my thumbnails. I don't know the code behind this software but for me: time saved on regenerating thumb for little bigger picture is lost on searching its entry in SQlite database + reading it from
hidden dir. Please correct me on this :)
For bigger images it is OK but not for such case. It would be better to have an Option for setting minimum image size needed for thumbnails.
BTW AFAIR some JPG files may contain embedded thumbnails already (in EXIF?). Does Daminion recreate thumb from bigger image to its own dir or use embedded one? How does it look like performance wise?
