If you do not have an account on Flikr, it is easy to set one up. Once you have an account you can add your photos and arrange them in albums and then share single photos or albums to the Skiathos Forum. Here's how:
1. Once logged into your Flikr account, click on the "Upload" button. Here you can select photos to upload or drag and drop them into the window. You will be able to add them to albums or create a new album.
2. After you have uploaded your photo and wish to share on the Skiathos Forum, select the photo and then click on the share icon.
When the dialogue box appears select "BBCode" and then copy the code in the text box.
3. Start a new thread or reply to an existing thread on the Skiathos forum. At the bottom of the text box select "BBCode".
4. Paste the BBCode into the text box. Select Preview (See pic above) and your photo should be seen. Add text or select Create Thread.
I've got an account with Flikr and uploaded one photo some time ago. I've today uploaded another half a dozen. I have so far been completely unable to create an album, so I'll come back to it after lunch.
