I am much with my friend Sandra on this topic.  However, often I post from personal emotion, a tie to the image whether if is derived from a personal part of me or from attachment to an image with which I am very taken and must share from an artistic viewpoint, to share with absolutely no idea how the image may be received by others.  Other posts are images I honestly believe are simply worth sharing and well done (within my limits of "well done") whether of  artistic nature or other such as illustration, nature scene or something of interest.   

I certainly want to post more images with which I do have artistic attachment but such has not happened..  I have several images planned in my mind like a painting to be done.  In front of me is blank gesso or unexposed image because the painting is not done yet for any medium but my mind.  When fortunate, on a moment of time I will create or will see what is already arranged for me and bring it to my artistic view and then post the image.  The artistic images...for those I am shy.  As for the illustrative ones, with those I am not shy and  post here with ease.  I believe some of my best images have received the least comments..."best" being in my point of view.

Post as you feel.  You can always decide to delete the image.  Personal gallery has the delete option and you are not obligated to maintain an image you decide later is not pleasing to you.  I will sometimes post images which mean something to me and hope others will see the same. An example is one of my later posts in the "atmosphere" genre.  Responses to this image surprised me and were very pleasing to my heart.
