Hi there,we have a absolut clean unmodified installation of latest osTicket 1.10., uploaded custom logos and inline images are stored in the database (table "file") but will not be displayed. The actual system info:osTicket Version     v1.10 (901e5ea)Web Server Software     ApacheMySQL Version     5.7.17PHP Version     5.5.38We know that images stored are displayed via file.php and the stored values in the database:A. That is the call of an uploaded custom logo:OSTICKET/file.php?key=nh8geiwca5magzzc9kxepjq30pq9as7y&expires=1500854400&signature=fbc545b10c901826899e7e7e51e7f16ada69f4e2B. This is the call of an attached image to a ticket:OSTICKET/file.php?key=zw-hec9w7u18suhopwof3mesviqq80ue&expires=1500854400&signature=bd07e7794ca52756626a9179aa631cb0167becd3C. This is the call of an inline image in a ticket:OSTICKET/file.php?key=wjltx517vjctvta7g1fs1gqjm4nwcmq8&expires=1500854400&signature=6f1bbf663e607eba590dd937b61fb068ff80fbca-> all images are stored in the database and the entries are looking correct-> online call generates the error: could not be displayed because the image contains errors-> download jpg and open it in Photoshop generates the error: unexpected end of file (eof)-> download png and open it in Photoshop generates the error: could not be interpreted-> please could you give us more details to "expires" > it's only checking the actual session, or?To get closer to that problem, we did the following1. We switched PHP version: 5.5 latest cgi, 5.5 latest fpm, 5.6 latest cgi, 5.6 latest fpm, 7.0 latest cgi, 7.0 latest fpm  > has no effect, error stays2. We tried different image types e.g. png, jpg > has no effect, error stays3. We tried attachments to filesystem > has no effect, error stays4. We tried downloading attached files > has no effect, error stays5. We tried other attachment types e.g. pdf > are working correct, no file damage6. We opened the stored blobs in file_chunk directly in Photoshop > are working correct, images are displayedAny ideas? Best regards, Jürgen

Hello, I had the same problem, this is how I fixed. PHP 5.6 Ubuntu 18.

class.file.php

function sendData($redirect=true, $disposition='inline') {
$bk = $this->open();
if ($redirect && $bk->sendRedirectUrl($disposition))
return;

    @ini_set('zlib.output_compression', 'Off');
//Add this line to clean the output to fix any problem with images
ob_clean(); 

    try {
        $bk->passthru();
    }
    catch (IOException $ex) {
        Http::response(404, 'File not found');
    }
}
