I followed several tutorials showing how to customize sitefinity controls (the Image gallery in my case). That worked all fine, but now I came to a point where I would have liked to customize the code behind. (Goal would be that from an image library only 3 pictures would be shown in a preview, but you could switch through all of them. Further, I'd like to give the first three images an additional (different) css class (like .first, .second and .third)).
I read this
and several other stuff but could not find out where
the complete code behind is shown, so that I know what I have to override and what not.
Likely that I missed a tutorial or a hint where to find it :)
Thanks in advance for your help!
