Oh well, I understand now.
I randomly stumbled on your photos in Rap of China so thought it might be helpful to talk through the thought process so you know what will be deleted and to give you a better sense of what to upload in the future. (I know these photos were uploaded before the discussion above so not blaming anyone... just using these as examples....)
In the screenshot below, the photos in the bottom row are all allowed in the gallery. They are published by iQIYI or the show itself. Those types of photos can be uploaded, assuming they meet the other guidelines (i.e., no heat index/popularity/ratings allowed, etc.).

All the photos above that row are from YHX's account and to be included in the gallery, per the guidelines...
"Keep the Gallery Title-Focused: An image should have a clear connection to the drama, movie, or show itself."
The only photos that nicely fit that criteria - that show a clear connection to the show - are the ones boxed in white (top left, and the left three in the third row). He is on stage AND doing something show related. The AND part is important because if he had stood on stage and just taken a selfie, that would not be allowed as the focus of the photo is on him, and not on the production itself. So those photos in white are ok for the gallery.
All the other ones are technically not ok for the gallery. They could be from any random photoshoot, and the focus of each photo is on the person and not the show itself. However, one could argue that he is showing off his outfit for the episode, in which case, fine but keep only one or two photos and remove the rest. Like in the top two rows, pick one or two (I'd do one with the shades and one without) and delete the rest.
Same with the photos on the bottom of page 2 of that gallery, and on pages 3 and 4. All the photos are focused on him and not the production itself. If the point is to show off the outfits, then pick one or two pics of each and remove the rest.
I would also add that if there is already an official photo of a particular outfit, then it's not necessary to add more from the cast member's account. For example, the official photos in the top row here show the same outfit as the 1st and 3rd pic in the bottom row. They are also similar camera angles so those two on the bottom row can be removed as they're basically duplicative.
Hopefully that gives you a better sense of what to upload.
We'll leave that gallery temporarily untouched for now so you can pick and choose which photos to keep and delete.
