Apparent limit of 10 inspiration photos... state that in the UI and prevent further upload

Trying to get Room Visualizer AI to apply a good area-limited redesign to an entire room, I uploaded the good AI output plus the 10 inspiration photos that went into it, when just the good AI output didn’t work.

When I clicked the button to generate the design, I got an error:

roomvisualiserai.com says

Error generating design: HTTP error! status: 400, message: {"error":"Unexpected file field: inspirationPhotos. Expected: roomPhoto, furniturePhotos, or conceptPhotos","diagnostics":{"unexpectedField":"inspirationPhotos","expectedFields":["roomPhoto","furniturePhotos","conceptPhotos"]}}

I acknowledged it and tried again — I had an error in a previous session where a second attempt worked), but got the same. So I deleted one of the inspiration pics and everything went through fine.

I’ve included a screenshot below as it might help identify the exact point in the code at which things fall over.

If there is a limit to the number of inputs in any area, it would be good to mention that up front in the UI, and also prevent the user from uploading more images/inputs than that.
