My learners can't access Flickr accounts as our firewall blocks the Flickr site. How can they upload images? 

They can use Outlook, Evolution, Thunderbird, Gmail, or any other email client to upload your photos to Flickr.

• Login to the Flickr account on a PC that isn't blocked by a firewall.
• Go to http://flickr.com/account/uploadbyemail/ 
• On the right hand side of the webpage, find the email address beneath Email your photos to this address. It will be some random words and numbers followed by @photos.flickr.com.
  Note: If you don't like the generated address, click the RESET button at the bottom of the page, under Refresh your address. When you have an address, add it to your contact in your mail client.
• Now go to the Add these tags each time textbox and add the tag(s) you wish to use. It might be beneficial to keep this rather general but separate from your other tags. You can specify more specific tags at the time you upload the image.
• Click the Save button.

You are now ready to upload photos from your email client. To do this:

• Open the email client and compose a new message.
• Use the Flickr generated email address for the To section.
• In the subject line, input the following:
  <photo title> tags: <your tags here>
  using any additional tags you wish to add to the photo (remember, you already assigned 1 or more tags for any email generated photos).
• Add the desired image to be uploaded as an attachment.
• If you want to assign a description to the photo, input it into the body of the message.
• Send the message.
  Your image will be posted to your Flickr account.
  

Note:

1. It is a good practice to do one photo per message to avoid posting conflicts.
2. Another benefit of using the email client to post is that you can give another person the ability to post to your Flickr account without giving them direct access to your other photos. When you want to stop them from posting to your account, simply go back and reset the Flickr email address.
