I've been there, done that for years. Dial up sucks so bad I didn't get to experience a lot (or any) of video posts. Many sites do limit the size of attachments and I always re size my photos to 'web' dimensions maximum of 800 pixels. I wondered why the quality of images posted were so awful with mostly sizeways camera photos, HPS lighting and out of focus. It doesn't really matter to the effect of the posted page as they are thumbnailed anyway. Any remarks about the other two matters?
