uploading production stills as evidence for a new title submission

Hello, I’m working on a new title submission (reference number 250918-001907-902200) and I’d like to clarify the process for providing production stills as evidence. Is there a way to upload production stills directly to IMDb, in the same way that we can upload evidence when submitting credits? Or, if that is not possible, is it acceptable to provide an external link (for example, a Google Drive folder or similar) where moderators can view the stills? Thank you very much for your guidance on this matter.
