SharpDevelop のフォームエディタで、ImageListがうまく動かないので調べてみたら

I had the same problem as you. #Develop seems not to be able to automaticly add the selected images to a resource and include them into the ImageList-Object.
The solution was to create a resource manual, add the images to the resource and load the images to the images-collection of the ImageList-Object whith the Add-Method.

手動で設定しないとダメダメですよ、ですと。めんどくさいですなー。
