$innertext = "<input type='text' name='$fieldname' value='$fvalue' id='$fieldname' style='float:left;margin-right:-2px;width:300px;' class='layui-input' /> <input name='".$fieldname."_bt' class='layui-btn' type='button' value='浏览...' onClick=\"SelectImage('form1.$fieldname','big')\" />\r\n";
有2处，都改成
$imgstr = ($fvalue=='') ? '' : "<img src='{$fvalue}' width='150'>";
$innertext = "<input type='text' name='$fieldname' value='$fvalue' id='$fieldname' style='float:left;margin-right:-2px;width:300px;' class='layui-input' /><input type='button' class='layui-btn' value='本地上传' style='cursor:pointer;' /><iframe name='upmy{$fieldname}fra' id='upmy{$fieldname}fra' src='' width='200' height='200' style='display:none'></iframe><span class='litpic_span'><input name='my{$fieldname}' type='file' id='my{$fieldname}' onChange=\"SeePicNew(this, 'divmy{$fieldname}view', 'upmy{$fieldname}fra', 165, '', 'save', 'my{$fieldname}', '{$fieldname}');\" size='1' class='np coolbg' style='cursor:pointer;height:30px;margin-left:-40px;opacity:0;width:85px;'/></span> <input name='".$fieldname."_bt' class='layui-btn layui-btn-normal' type='button' value='站内选择' onClick=\"SelectImage('form1.$fieldname','big')\" /> <div id='divmy{$fieldname}view' class='divpre'>{$imgstr}</div>\r\n";
完成后，清空浏览器缓存和临时文件，重新刷新后台，测试效果，如果无效，打开浏览器无痕窗口测试
