We’d need debugbacktrace () data to determine the root cause. Or you could use the mimetype returned by fphpgetimagetype/fphp instead. This function can be found in any PHP version similar or greater than 5.2.0. Knowing where the warning occurred doesn’t help us much in determining the root cause. The imagetypetoextension () function is an inbuilt function in PHP which is used to get the file extension for an image type. for me to can work with getimagesize function or exifimagetype when i choose a file which is php and i change the extension to jpg ofcourse my codes say me this isnt an image but again show that. $imageErrors = "ERROR! File size was too large! It must be under 1MB. A common cause for this warning is there is something wrong with the file’s path or it refers to a file that cannot be accessed in the way that exiffiletype () requires to work properly. Also, what changes should be made to make it more secure? So far it's working without any obvious problems, but I would just like to have the script reviewed for possible issues. By default, users have a generic profile image, but if they use the script to change their picture the database is updated to reflect the new filename. I have a form with html 5 multi uploads which embeds the image files in a pdf report & sends attached files & pdf via email & displays the record in. It then converts it to png, saves it to a folder outside the web root with a randomly generated name, then moves it to a specific folder inside the web root with a new filename that matches the user's username. I have a PHP script that uploads an image file, checks it for size, extension, and type.
