if you like my images enough to want to use them you can only do so with my written consent, especially if you intend to use the images commercially, in which case I would expect payment. If you don't want to use my work commercially but you would like to post one or more of my images on your website or blog please ask first. I'm sure I will have no objections as long as you link it/them back to my blog as your source.
My prints are the way I make my living ... as Diane says we all have bills to pay so whilst it may be flattering to be copied it is much more satisfying if I get paid for what is after all the result of my hard work.
AND .... please note, if you are tempted to ignore this polite request, you should know my work is collated and stored legally. I DO have proof of ownership.
