  1. I am using this script for image uploads. https://www.w3schools.com/php/php_file_upload.asp I noticed that with some of the image uploads, I would get the error "Sorry, only JPG, JPEG, PNG & GIF files are allowed." The images i upload are one of the file types listed above. So I am wondering why i would get an error for some images but not others despite all them of being the same file types? Can you tell why judging from the script?
  2. The image uploads fine but I get this weird gibberish code after I submit. It goes away after i refresh the page. JFIF>CREATOR: gd-jpeg v1.0 (using IJG JPEG v90), default quality C $.'
