I would like to place in a same figure multiple floats with each a subcaption, however, even with the subfig package I cannot achieve the desired effet. I would like to have in a left column one long image, and next to it on the right a column of the same height with 3 images this time :
I would really appreciate any help on how to organize my subfloats, or even a recommendation for another latex package.
I tried another way with the multicol package, but then I ran into trouble with the alignment of the subfloat environments. So I would suggest to use this version (but I could also provide the other).
The same approach that localghost suggested, but using the subcaption package (you need a recent version of the caption package, 3.x at least if I recall correctly).
