If this is for some one who is a newbie to ask a question then my question is how do you adjust the file size of you render?  I have made several renders but the file size for them are too large to be uploaded here, so how can I adjust the file size so it can be uploaded here?  Also it should be noted that as far as photo shop goes it is so basic that you might as well say that I do not have one.  Thank you for any help.
