Hi,

and here a 1st problem including (some) JPGs which are created/converted using "convert" 
from ImageMagick (using ImageMagick-6.8.6.9-2.28.1.x86_64 from openSUSE 13.1 -- just in case...)

btw. -- I'm using a decent standalone context installation, full log file attached...

running "context j1.tex" I get

	LuaTeX warning: arithmetic: number too big
	graphics        > inclusion > limiting natural dimensions of './IMG_9712c1_bad.jpg' (height)

	tex error       > error on line 1 in file /home/harald/tex/Indien-2015/j1.tex: ! Dimension too large

for "IMG_9712c1_bad.jpg" which was generated with this command:

     convert -resize 632x330 IMG_9712c1_ok.jpg IMG_9712c1_bad.jpg


using other tools I can't find any problem with that "bad" jpg, only context complains:-(

what's wrong with "IMG_9712c1_bad.jpg" ?


tanks,

Harald
