To post to Flickr, use one of the handy uploading tools (for a batch), the web upload form (for bits and pieces), or send your photos or video in by email (great for cameraphones). As your collection grows, you can organize it into sets and see everything via your archives.
This site has links to all of the upload options:
Flickr tools for uploading
I recommend you download the Flickr Uploader 3.0 from this site, although you can upload via the normal upload button.
Click Download and then Open from the download window and follow the Wizard prompts to place the application in the Program files and a shortcut on the desktop.
Simply click on the shortcut and drag and drop files into the window. Set your privacy options then click Create A Set button. Be patient whilst they upload!
BUT….
You can only upload files smaller than 1Mb each
Do not upload more than 10Mb worth of files at a time
I advise you to prepare your files first so that you can upload easily and minimise your monthly upload quota (around 100 Mb)
Use Adobe Photoshop or a similar photo editing application to resize your images for the web:
PREPARING YOUR PHOTO FILES FOR UPLOADING
In Photoshop:
Open the file > go to Image menu > Image size and change the longest side to 750 pixels. This could be the width or the height depending on if its portrait or landscape format.
Then go to File menu > Save for Web and Devices. Go to the pull down menus to the right of the image and select > jpg and maximum. Click Save and save in a new folder called something like ‘Flickr Beach resized.
Note: Be careful NOT TO OVERWITE your original files!
UPLOADING FILES TO FLICKR
1. Click on the Choose button > select your files from the resized images you just saved
2. Click Upload. Flickr will show you how much memory of your monthly allocation these consume. It will take a while to upload - maybe time for a coffee!
