is there a way to batch edit dates on photos and albums?

spike

Hi,

I use GraphicConverter to scale my full size images down to size. This means the "date" of the image is then wrong (it's the date I scale the image). Manually going in and changing first the album, then going back in and manually changing every image back to the correct date is tedious.

Is there a better way to do this?

(I looked at the MYSQL database. My host requires using phpMyadmin via web interface. It looks intimidating and confusing.)

Hoping someone can help.

Zenphoto also uses EXIF information if existing. If I am not wrong Graphic Converter supports EXIF, too. Or you could this to edit the EXIF information: http://www.macupdate.com/info.php/id/25847/setexifdata

If you put the date in EXIF or IPTC fields of your images, Zzenphoto will pick it up and use it. If there are already dates in your database, the easiest thing is to use phpMyadmin and drop the date field in the images database. Then re-run setup to restore the field. Then use the refresh metadata button in admin to cause zenphoto to retrieve the date from the image.

Thanks for the help.

acrylian, I know Graphic Converter lets you strip EXIF data. Though, I haven't been able to figure out how or if I can edit a date into it. The documentation is sparse but I'll keep trying that path. I'll also save that other app's bookmark for if/when I update from Panther. That's a good idea but I didn't find any editors over at Versiontracker for Panther, and I'll keep looking.

sbillard, I'm not exactly sure what this means (remove the date tables?) or how to do it...

use phpMyadmin and drop the date field in the images database

but I gather if I can remove the dates on the images then refreshing the meta data in the MYSQL would set the dates to the image's EXIF. Would that happen even if I didn't delete the dates from the db?

If it does then all my images will end up wrong again if I ever refresh the metadata. I stipped the EXIF data from my images using Graphic Converter because my digital camera puts all kinds of personally identifiable info in the EXIF data, camera serial number for example. That's why there's no date to override the date that I resized the pictures.

Thanks for you help.

I will keep

You really should be selective about what EXIF/IPTC data is removed. Some of it is quite useful. If you refresh metadata, a date will be stored. If there is none in the EXIF/IPTC it will be the filemtime of the image. So, I guess if you have stripped all the EXIF/IPTC data from the images there is really no point in doing a refresh metadata.
