TJPEGImage inherits Width and Height properties from TGraphic.  You don't
need to convert to TBitmap first:

    AnsiString MakeJPEGHtmlWrapper(TStringList * L)
    {
        //...
        TJPEGImage *jpg = new TJPEGImage;
        //...
        jpg->LoadFromFile(B);
        //..
        A += ( "width: " + IntToStr(jpg->Width) + "px; height: " +
IntToStr(jpg->Height) + "px; \">" );
        //...
        delete jpg;
        //...
    }

Yes.

Not unless you open the files yourself and decode the jpeg data manually.
