Hello, hope you’re doing great, I really liked the code and it helped so much but I have a little problem, is that I can’t adjust the seize of the image that I’m uploading, can you help me and tell me how to get a solution for this problem? thank you so much and have a great day !
Hello,
You can do it with CSS, like :
#preview {
width: 640px;
}
