When building an ImageList at runtime is there a quicker way rather than
using the Add()..
i have been loading 500 images of the same size 75x75 so they are quite
small but the program slows dramatically while this is being done..
It might not help that i am having to call the images in from jpg first and
assigning them to a bitmap prior to adding them to the list., but it still
seems a bit slow building the list..

Any speeding up ideas very welcome..
