Just a test - forgot I even had a postimage acct. Thanks for your cooperation and reminder. Other images in my default account are private so I want to see that only this image is available. ;-)
Link to Postimages: PostImages.Org
For others - sign up is just enter an email & confirm email.
Checking the faq there was nothing I saw suggesting you were allowing them copyrights to the image and they say they're there forever.
Some of my stuff was several years old.
For FR - upload or copy picture URL (address), select "share" and then copy the "Direct Link" URL and then paste into the standard < img src="http://yourimgsourceinfohere.jpg"> format to have your pic pop up.
Use that one as if the original source of the pic goes away your pic is gone.
Thanks timestax! ;-)
