SIMDRAGON .... hello and THANKS MUCH .... I think I understand all that .... Just a question (my FIRST pc....lol) .... If I have a 800x600 image that I 'upload' here without a 'thumbnail', it will obviously come up in those dimensions, as I have done that already .... I have "picture it 2002 premium" software program .... I see where there is a place where I can 'thumbnail' pics as I 'save' them .... If I 'check' the white square box to 'thumbnail' it, will I have to have a 'certain sized thumbnail' to 'fit' here at renderosity??? .... or, by me just 'thumbnailing/checking' the box on my ''picture it'' software, will it take care of it for me? .... thanks, again to you and ALL others willing to use their most valuable time to help out a complete 'idiot' .... lol.... roadrunner69.
