wrong link in oilpainting tutorial

[LaurentBerger]

Something is wrong in this page . Images links https://docs.opencv.org/trunk/images/baboon.jpg and https://docs.opencv.org/trunk/images/baboon_oil_painting_effect.jpg are :
The requested URL /trunk/images/baboon.jpg was not found on this server.
In my local build image links are good but wrong in buildbot too (http://pullrequest.opencv.org/buildbot/export/pr_contrib/1779/docs/dd/d8c/tutorial_xphoto_oil_painting_effect.html)

hi @LaurentBerger , i have some suspicion here:

your Images folder has a capital I , while a lowercase one is expected

(the linux filesystem is case sensitive, i guess your images could not be copied because of this)
((this might also explain, why you can see it in your local docs (running on win ?))

Please use lowercase for file names / links if possible.
