This method of uploading photos, or files, is an alternate to using email to send photos. (Note: FTP is still a superior method of uploading.) Many times the email will only take so many photos, and you don't know until you send them if you were successful. Email requires you to attach the photos to the email, this method is similar in that you choose photos one by one to send in a batch. (If you know how to zip files, you can zip all the files in to one zip file and just upload that single file.) There is no limit on the size of the photos or number of them. (I have a arbitrary total limit set at 500 MB)
To start, you will log into the following URL. I suggest that you save it as a Favorite or Bookmark if you plan on uploading frequently.

You will see the following screen. (The following are only images of the actual login screens, you can not use these to login with.) Use the password to login. It is currently the same one as used for the ftp programs. Email the webmaster for the password.

After logging in, you will see the upload screen as shown below. Simply click on [Choose] button. A window will pop up so you can click your way to the correct folder for the file/s you want to upload.

Highlight a single file, click "Open" and the file will appear in the upload line.

Since you can only choose one file at a time, click "Add another file", and add a second file. Continue until you have added all the files you want to upload. When done, click the [Upload] button.

When you login again you will see the files you have previously uploaded.
