Bug Description
I am using scribus 1.4.6+dfsg-4build1 on Ubuntu 17.10 (artful). Create a new Scribus document and just insert one JPG compressed picture (Sleeping_
Compression Method: Automatic
Compression Quality: Maximum
Unticked Maximum Image Resolution
The resulting PDF is multiple times bigger than the original JPG picture:

I expected that the resulting PDF just embeds the JPG picture without modifying it, but this is not the case. I don't see a way to let Scribus embed all JPG/PNG images unmodified in the PDF.

From https:/
"A(nother) user recently noted on irc that progressive mode JPEG induced huge PDFs, when not-progressive type just did fine PDFs (i'm not sure but i seem to remember that this user said it was a new behaviour)."
This is exactly my problem. When I convert the picture and remove the progressive mode, the resulting PDF is small.
