Block Image Pasting from Clipboard when Text Present

[jw-bakerross]

I have users copying data from Excel spreadsheets which, when pasting into LibreChat, includes the image preview.
This is causing very high input token usage

I know that they could paste with Ctrl+Shift+V instead but it's not possible to guarantee that a user will remember or bother to do this every time.

Is there currently a way for LibreChat to block images from being pasted into the chat box if text is also present in the clipboard? Or outright block pasting images into the chat box?
I'm fine with users being able to upload images with the file upload button.
