It's ok. It's not a big deal. Mistakes happen. Hiring Melanie Tran was one.
Here's a trick: for pages with working DPL galleries, if your image is categorized correctly, just go to https://codelyoko.fandom.com/wiki/PageNameHere?action=purge and that should get the image in. If that doesn't work, contact me or one of the other admins. There's usually at least one of us online in the Discord server, and the Message Walls work too.
Oh and one more thing... I cannot add images to some pages. I wanted to add image with Aelita carrying Yumi in the Mountain Sector in Evolution but I cannot add that image to any page. What should I do?
Some of the galleries aren't meant to be edited by humans. Some of our galleries are auto-generated using DPL. Since we categorize the images anyway, it's sometimes easier to just do that instead. Which page were you try to add the image to?
It's been added. Yeah, that's one of the ones with a server-maintained DPL gallery. In the future, if you find one of those, you can usually fix it by going to https://codelyoko.fandom.com/wiki/PageNameHere?action=purge
