For a really, easy way to email your photos use Paint Shop Pro. Corel has a tutorial to show you how. No more sending oversize files that aggravate the recipient. No more guessing the optimum file size to send. Paint Shop Pro painlessly walks you through the process. Choose embedded or attachment, pick your size (three easy options, plus original or cell phone), and send them off to your chosen recipient.
Here, I chose to embed (nice option) the file. Optionally, I could have chosen to send the file as an attachment.
