'Copyright'!

My post today is on hold.
Why?
Because of 'Copyright', on a particularly fine photo of a Robin that isn't mine!
In this case it belongs to a professional photographer, who I understand wants to protect his images, his living, so I have sort his approval.
But, I do note that using pictures that are not your own seems to have become a major issue!
I've never thought it necessary to safe guard my own, they're just snaps to me!
But, I'm beginning to wonder, as every time, I turn round re using, innocently on my part, a photo of others on my Blog, despite always making a point of giving Credits/Links to their source I find 'Copyright Restrictions' attached.
And, I will add this is not an attack @ the photo permission I am waiting on - it's a personal reflection!
However, I do begin to wonder about my own photo's posted daily on my blogs???
Okay, most are just simple digital pictures, quickly taken, but some I am seriously proud of, yet I've never thought to protect them.
I photo for the fun of it - it's my hobby/my pleasure - my blog's my beneficiaries!
I'm proud to see / share my photo's elsewhere!
Unless that was, to a commercial money making site using them without recommence to me, when I so, need cash.
Not that has happened or is likely too!
BUT, I guess that is the concern!
We share images freely here, but where do they end up via Blogger???
