Thumbnail generated even when "Use built-in-thumbnail" is selected
- I have EM2 (B2096) on Mac OS X 10.6.1. My thumbnail settings are:
- Size: Variable
- Quality: High
- "Use built-in-thumbnail (if available)"
I have JPEGs from my digital camera (Canon EOS 40D) with included thumbnails in my catalog.When I select "rebuild items", new thumbnails are generated (display changes and catalog size increases). Is there a way to avoid this, and is there a way to remove these unnecessary thumbnails from the catalog?The reason I do "rebuild item" is to update exif info display within EM after adding GPS info with an external app, but the thumbnails are also regenerated for files that have not changed since the import in EM.ThanksRainer

It might overwrite that field when you sync metadata. I'm not sure of that, and I don't think it would. But I can't test it because I don't have a file that has the data written to it by your app. In general, Mac doesn't write GPS data. But if we have an empty IPTC field we'll overwrite what's in the file's metadata when we sync. So for instance if you have people in an IPTC field in the file metadata, but not in Expression Media. Then you sync and export, it'll wipe out the people field in the file. That's because we overwrite all the fields, without merging.
Of course, if the GPS is written to the EXIF data, you should be safe.

If you export the hierarchical keywords, they will be reimported.
Removing thumbs from a catalog is really easy. Select all under the Edit menu or with keystrokes. Hit the Delete key or go to Edit --> Delete. (Do NOT click the X on the toolbar. That will delete media files from disk.) When the dialog box comes up, click Remove from Catalog.

- I've reproduced the issue. This looks to be a bug. The only workaround I can think of is to delete the images from the catalog and reimport them. There's a problem with that, though:
If you sync metadata without having the GPS stuff in the catalog, Media may overwrite the GPS data in the files.
Your best bet would be to sync metadata, then add the GPS data, and then finally delete the images in the catalog and import them again. That way you will write your ratings etc. to the files and that all will be imported again.
I'll report the issue to the product group.

Anita Oakley - Now I'm confused. EM might delete the GPS from EXIF? On re-import or only when syncing metadata?I thought EM on Mac does not write any GPS data at all?Rainer

- Thanks for the Info. I use Exiftool (actually a graphical frontend) to geotag the images, and it writes GPS info to EXIF. I tried with one file, and syncing metadata did not overwrite it.Another question though: if I sync metadata, delete from catalog, and re-import, and sync metadata back to the catalog, will hierarchical keywords be restored?An additional note: an option to remove all thumbnails from a catalog would be really neat!

- Actually, I was talking about removing generated thumbnails from the catalog, not removing entries for the media files.
- Oh - no, once those are generated, you have no way to remove them and go back to the built-in thumbnails other than reimporting. The good thing is that if you have syncronized the media info, it'll come right back in with the import.
