Hide it in a pixel of an RGB image: An RGB image pixel has 3 bytes, i.e. a range from 0 -- 2^(24)-1, corresponding to a range from 0 -- 16777216.
That should be enough for your relatively small numbers.
How to do that you can find nicely explained in
Werner Bailer: Writing ImageJ Plugins—A Tutorial, on p. 17
which you can find here for example:

Hope it helps

Betreff: finding info from .TIF file
I Am a newbie in imaging but for a riddle I need to find some information out of an TIF file.
I tried all the basic options using IMAGEJ but did not found what I was looking for.
This is the link to the image:
http://nijhuis.me/Geocaching/Up_in_the_air.tif[
http://nijhuis.me/Geocaching/Up_in_the_air.tif]
I need to find X.XXX and Y.YYY
Note. The value of X.XXX must be between 4300 and 7800
The value of Y.YYY must be between 0000 and 2900.
I hope someone can give me some useful advise.
