When an image is pasted into the chat input, the attachment is always named Pasted Image (then Pasted Image 2, Pasted Image 3, ...), even when the image comes from a file on disk. With several images attached, it is hard to tell them apart, and the name the user chose for the file is lost.

Pasted images often do come from a file:

• a file copied in Explorer/Finder, or
• a screenshot tool that saves the capture and puts the file on the clipboard (e.g. ShareX on Windows).

In those cases the paste event carries the file, and VS Code already resolves its path. For example, a ShareX paste arrives as ShareX_Region_capture_1.png with its full path.

Proposal: name the attachment after the file (file name only, not the path), e.g. diagram.png, and keep it unique with a counter before the extension (diagram 2.png). Images without a file on disk (raw clipboard bitmaps) keep the name Pasted Image.
