Right you say but this is something we can not reproduce using the default latest code on several different installs.
You have refused all attempts that we have asked several times for access to your install to assist and test so given this there is nothing more I can say on this issue.
I have explained exactly how things work and that second and third images can be the same image only the first image is checked.
Basically if you want support on this issue you will need to be running unmodified files and we will need ftp and admin access. If we can not reproduce any errors then obviously we need to look directly at whats so special about yours.
