Hi Harald,
how about converting the JPEG files with ImageMagick with two
directories (such as print-quality and screen-quality)?
If you use the same image file names, you could also use modes:
\enablemode[print]
\startmode[print]
\setupexternalfigures[location=/home/user/project/img-print/]
\stopmode
\startmode[screen]
\setupexternalfigures[location=/home/user/project/img-screen/]
\stopmode
\starttext
\externalfigure[image-filename.jpg]
\stoptext
As long as you use the same filenames and the right mode, ConTeXt will
choose the right file for each format.
BTW, I don’t know whether ConTeXt can shrink image quality, but I think
this workaround could do the job.
I hope it helps,
Pablo
