file upload button

[jgmtex]

I don't know much about web page design. I'm teaching myself. I was on a trip and I want to add an upload file button on a page so that other people from the trip can send me their pictures and I can put them on the web. I am using frontpage to design, and yahoo.com is the server. It would really help if someone could do a step by step process for me. Remember I don't know much about using codes, so please be nice and make it literally step by step.

Thanks in advance,

James

Hey everyone!!

I finally found the script i needed on hotscripts.com. It is ONE php file. On my server, i have to behind an encrypted password page. That I found on dynamic drive. (http://www.dynamicdrive.com/dynamicindex9/password.htm)

The file is very easy to use and lets you customize the file extensions to accept and the file sizes. It also creates a log of all files uploaded and a folder to store the files.

It wont let me attach a php file so here is the code

<?php
//vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
// You may change maxsize, and allowable upload file types.
//^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
//Mmaximum file size. You may increase or decrease.
$MAX_SIZE = 100000000;

//Allowable file ext. names. you may add more extension names.
$FILE_EXTS = array('.zip','.jpg','.png','.gif','.doc','.pdf','.eml','.idx','.npc','.qdf','.qel','.qph','.qtx','.qsd');

//Allow file delete? no, if only allow upload only
$DELETABLE = true;


//vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
// Do not touch the below if you are not confident.
//^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
