photos[] is an array of photos names then,

foreach($photos as $key=>$value)
    @$blocks .= '<div><img src="'.$value.'" onload="img=this"><img src="remove.png" onclick=remove_image(img)></div>';

so when clicking on the remove icon for the first photo it works just fine, but the others shows this error:

ReferenceError: img is not defined

    Thank you LukeGT, your answer is right, but I found it better to use jquery to handle it,




    to remove the whole div.

    You should refresh page when clicked delete button.

    The img variable is being stored globally, which means that it's getting overwritten each time a new image loads. You should instead assign the images unique ID's, and have their remove buttons remove the image by ID. For example:

    foreach($photos as $key=>$value)
        @$blocks .= '<div><img src="'.$value.'" id="img'.$key.'"><img src="remove.png" onclick=remove_image(document.getElementById("img'.$key.'"))></div>';

    (I'm not super familiar with PHP, so sorry if I made a syntax error somewhere)
