[Gimp-user] Orientations, Copyright Notices, metadata, and resized layers

[Ruben Safir <ruben mrbrklyn com>]

Hello

I've been using the GIMP for decades at this point.  It has been bothing
me that of late (and I am old so late can mean years :) ) that I rotate
the image 90% and it doesn't prent in the correct orientation on my
websites.  This is getting to be a real PIA.  With JPGs, you can't just
remove the EXIF data without reprocessing the entire image.  I have
resorted to trying to edit the files in VIM and removing the EXIF data.

But that has lead me another issue, and this is ration serious.  It is
easier to so than tell:

Is the GIMP declaring my images and Public Domain copyright?  That would
be not cool.


One final thing.  When I resize images now, I am left with an Layer or
Canvas that is still the original size and I have to manually flatten
the image.  This is a huge time waster and not the original behavior of
the GIMP.  Maybe there is an preference option on this?
