Upload error: Image data does not represent an image

When I upload this album with web locations, the system console shows this error message:
Make album: 0.54s
Album upload: 0.675s
Total upload: 1.299s
java.io.IOException: Error while adding album. Server reported: java.io.IOException: Image data does not represent an image.
	at se.datadosen.jalbum.Notifier.albumAdded(Notifier.java:127)
	at se.datadosen.jalbum.Notifier$1.run(Notifier.java:153)


The uploaded album seems OK, so why do I get that silent error message?

Thanks for reporting. Open that album project in jAlbum, then open jAlbum's system console and issue the following:
rootFolder.getThumbnailPath()
What does it return?

Please make a minimal album project that behaves like that, zip it and attach it here. I can't reproduce it.

Thanks André. I made and uploaded that gallery, but "unfortunately" it works :-/. I'll keep an eye on this. Luckily it's not an error that hinders usage.

Well David, I did discover that it depends on the server:

I see this error only if I upload the album to my Strato server, to URL
https://www.andrewolff.nl/FotoSerie/WaddeneilandenTest_PS/

If I upload it to the jAlbum server, to URL
http://andrewolff.jalbum.net/WaddeneilandenTest_PS/
I do not get the error message.

I see the same behaviour if I use the Minimal skin instead of the PhotoSwipe skin.

Edit:

I wonder could it be caused by the https protocol used in the Strato URL?

If I upload the album to jAlbum there is automatically a http page opened, how can I change this so that a https page is opened?

Could it be that your server doesn't allow random access to images?

I don't know what you mean and I don't know how I can check that!

It seems to be our server that generates that message when it tries to fetch the album thumbnail when adding the album to the profile page. I don't think it has anything to do with web locations. Have you tried to add any album uploaded to your server? (It of course works when I try to manually add your album.)

You are correct, I get that error message also with albums without web locations.

How can I prevent thatan album is added to the profile page?

Sounds like it's related to this - slightly different situation, but....: https://jalbum.net/forum/thread.jspa?threadID=52621

You'll have to sign out from the jAlbum client...

But if I just figure out a way of reproducing this error I should be able to fix it.

I have now added some logging, so if you try to add that album again that fails I can see what's happening.

I see still the same in the system console:

Album upload: 0.751s
Total upload: 1.415s
java.io.IOException: Error while adding album. Server reported: java.io.IOException: Image data does not represent an image.
at se.datadosen.jalbum.Notifier.albumAdded(Notifier.java:127)
at se.datadosen.jalbum.Notifier$1.run(Notifier.java:153)

No logging is visible for me.

I use the jAlbum uploader already 10 years to upload albums to my Stratoserver, but I can't remember that I ever had seen this error message, so I guess there is recently someting changed which causes this problem.
