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:





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,
