Problem rotating pictures

[Animor]

Hello,

I hope this is the right forum.

I have just installed Coppermine 1.5.8.
Some users have uploaded pictures, and I noticed few pictures are rotated. However, when I tried to rotate a picture to the right position, it didn't work well.
Preview looks fine after rotation. Then I saved picture and saved thumbnail.
Now what happened is strange: the picture frame was rotated, but the picture itself remained unrotated and now it's also stretched.

An example of "stretched" picture after rotation:

Did I do something wrong? how can I rotate properly?

Thanks!

Thank you! you are right
I feel a bit dumb... I did refresh (f5) the gallery, but apparently I had to do it when viewing the rotated picture.

No upload issue. Moving to misc.
