this problem:

foreach (fileinfo fi in finfos) {     images.add(image.fromfile(fi.fullname)); } 

image.fromfile open file handle, , won't close until dispose of image. you're trying move file without disposing of image has file open first.

i suspect if dispose of relevant image in button1_click , button2_click methods (being aware if it's showing in picturebox you'll need remove there first) you'll find works.
