How to place company logo in the Suite CRM application?

I suspect that the problem is in the file: modules\Configurator\UploadFileCheck.php
$returnArray = array();
if($json->decode(html_entity_decode($_REQUEST[‘forQuotes’]))){
$returnArray[‘forQuotes’]=“quotes”;
}else{
$returnArray[‘forQuotes’]=“company”;
}

or somewhere in the function uploadCheck(quotes) file:\modules\Configurator\tpls\adminwizard.tpl
switch(file_type[‘data’]){

//error in getimagesize because unsupported type
default:
alert(SUGAR.language.get(‘Configurator’,‘LBL_ALERT_TYPE_IMAGE’));
document.getElementById(‘my_file_’ + forQuotes).value=’’;
}

The file name is short, with no spaces, normally displayed on the screen (screenshot in the previous report), the picture size is small logo.
However, the program performs a default block
