I'm sorry I find that a rather forced logic. As we have seen the image  
will not be _identical_ due rounding errors and such , that does not make  
the existing choice of jpeg_quality "irrelevant". It represents the users  
choice of size/quality trade-off.

I see no justification to discard that choice as irrelevant.

File | Save should save the image as it is. Save_As is there as a means to  
change things.

Gillermo's real world example where the file size shrank by a factor of  
two and the quality took a serious hit can hardly be described a  
straight-forward save. It's doing a major change to the image and changing  
the compression parameters (quality and sampling_factor!), this should  
only happen through the Save_As with a full dlg.

Allowing the user for redefine the default is fine but I see no bearing on  
this issue. This is not a lifestyle choice it's a per image choice. It's  
irrelevant to this discussion.


I'd always assumed that the default 85 only applied to untitled images on  
the first save not that it was silently forced on an unwary public as some  
sort of hidden "gimp knows best" feature.

Abritarily throwing away half the image data without so much as a 'by your  
leave' , incredible.

I'm really surprised that you dont see this as a bug.

I would ask you to seriously consider if this is appropriate. Please take  
time to reflect on this before replying and preferable sound out a few  
other opinions.

Thanks for the reply.
