Contentscrambling on .jpg-Upload

[Stoffel]

I'm uploading a bunch of JPG-Images, Compressed and resized properly by IrfanView. As the bunch (about 50 pictures) is uploaded, my Gallery-Programm often gives Errormessages, because the content of the pictures is scrambled. This happens just sometimes, about 5-10% of the Pictures. Usually two parts of the picture are switched.

As I reupload the Pictures, everything ist fine...

Scrambled Image-Content

[Stoffel]

Sorry, forgot Version-Number...
3.2.0-rc2

As I didn't expect the error, I don't have logfiles yet...
I try to get some as fast as possible...

[Stoffel]

Finally an Logfile of Transmit which scrambeld Pictures... Some are not only scrambled, but totally messed up with colors, enlargements and so on...

Still active in Version 3.2.2.1

Are you accidentally transferring the files with ASCII data type? See ​http://wiki.filezilla-project.org/Data_Type

[Stoffel]

Nope.
Anyways, as only some of the transferred Images (about 5%-0%) are corrupted, there must be some wierd reason...

[Tim Kosse]

Broken routers and/or firewalls can destroy your files. Please run the network configuration wizard, make sure the test at the end succeeds. As long as it fails, correct transfers cannot be guaranteed.

At first, External IP was broken, but I fixed it... maybe this will already solve the problem, but I'm notsure why the last Error happend...

BTW: I didn't attach the Logfile yet because it is too big. If you tell me, which part is important, I can cut it out....

[Tim Kosse]

Clear log. Connect and upload the file. If file is broken attach the log of that attempt. Otherwise start over and retry until it fails.

Also, please attach the original image to the corrupted one also attached to this ticket.
