Describe the bug
I think I managed to reproduce this bug https://reports.phpmyadmin.net/reports/view/89249
Warning in ./libraries/classes/Image/ImageWrapper.php#95
imagecreatefromstring(): Data is not in a recognized format
It happens when the structure of the image column is changed and rows contain a filename for example and also a image.
How to Reproduce
Go to https://demo.phpmyadmin.net/QA_5_2/index.php?route=/&server=1 (MariaDB)

CREATE DATABASE IF NOT EXISTS ` test` ;
CREATE TABLE IF NOT EXISTS ` test` .` test` (
` id` int (11 ) NOT NULL AUTO_INCREMENT,
` image` longblob NOT NULL ,
PRIMARY KEY (` id` )
) ENGINE= InnoDB DEFAULT CHARSET= utf8mb4;
INSERT IGNORE INTO ` test` .` test` (` id` , ` image` ) VALUES (1 , 0x0);
INSERT IGNORE INTO ` test` .` test` (` id` , ` image` ) VALUES (2 , 0x89504e470d0a1a0a0000000d4948445200000001000000010802000000907753de0000000f494441547801010400fbff00ffffff05fe02fe49666e2b0000000049454e44ae426082);
