Want to upload a picture, can the foreground with input type= ' file ' name= ' file ', backstage with something like $_post $_files[' file ' to receive, $_files this thing is also a super global variable, there is [' name '],[' size '] these properties. Front desk more than a form field, the background naturally also corresponds to one more column, SQL statement ALTER TABLE tablename add column pic varchar (50). Front desk backstage everything has, put data into the database.

$pic =$_files[' file ' [' Name '];

"INSERT INTO tablename values (' $pic ')";

We're going to have to show the pictures after we've plugged them in. Just find the upload temporary storage point, the picture out of the good.
