Is it at all possible to have say the first left image be of size 16x16 and the second one be 8x16 (same height, different width)? Thanks.
Not using the public object model. There are some ways to hack this out that come to mind...you could create a 24 x 16 image, and use GDI+ to blit the two images to that new one, and add the resulting image to LeftImages. You could also use the IUIElementCreationFilter interface to add two ImageUIElements, one for each image, in place of one that would appear if you added a dummy 24 x 16 image to the LeftImages collection.
I guess I'll have to decide if I want to make that time investment. Thanks Brian.
