Forum:I need help with an error!

This morning, I was trying to customize the achievements on Poptropica Fashion Wiki. I was attempting to update the pictures in the achievements "Emerging From The Darkness", and "Rich and Famous". However, whenever I tried to update the pictures, it just reverted back to the old ones!

I tried everything I could do to fix the photos. I reverted to default numerous times, I asked for help from Poptropica Wiki, and even tried shutting down my computer and turning it back on. IT STILL DIDN'T WORK!

If anybody can fix this error, I would forever be in your debt. Thanks!

PS: These are the pictures I was trying to upload. I think it is pretty obvious which one goes for which achivement.
