Exif Data are not there

No, they aren't as far as I know. It's a long shot, but are you sure that when you save your jpegs, you are retaining the exif data?

Of course the EXIF-data are retained. If not, then Blipfoto don't accept them (the exposure date is mandatory).

Oh well, only trying to help. The new blipfoto system doesn't seem to care about dates any more.

Thank you! But to my experience, new photos are always uploaded to the exposure date. If I try to upload a photo with a date that is already taken, the system protests.

Yes, it does, but now I think you can post a photo against any empty date, not necessarily the one when it was taken. In the old Blip system, photos with no exif data were held for moderation -- I did it by accident a couple of times.

Anyhow, I hope you eventually get a response from BlipCentral! Lights on but no-one home.

Now I have invetigated this in depth. And you were right on all points.

My Exif-data were not reatined through the upload. There was some kind of error setting in my picture processing program. It is a bit embarrassing for me to admit that. :( The good thing is that I have resolved this problem.

It is possible to publish a picture with empty Exif. It will be posted at the posting day. On the other hand, it is not possible to post a picture on a date that already has a picture. If you do, the system ignore Exif and post it on the posting day. If you manually choose the occupied date, you get no error message, but the system refuse to post it.

Well, that is about what I have found out. Maybe I'm wrong on some detail. Thank you for showing interest. Thanks to you I got the incentive to go to the bottom with the question.
