Reckless the policy and guideline were both updated last year to move away from the era of small screens and slow downloads this was around the time en WP sucessfully pushed the Foundation techs to move the whole 300 projects gradually from 180px to 220px default thumbnail size great In fact for readers with slow connections it s often better to have a larger display in an article so they are less likely to need to double click on the original originals are often huge and take much longer to download I am generalising here and individual cases need to be judged on their merits BTW I encourage all editors to arrange and size images WRT narrow to wide window widths and font sizes skins etc Just move your window through from narrow to wide to see what a difference it makes in the way text and pics interact For this reason left side placements need to be treated with caution when there are right side pics in the same section Also I recommend squashing all of the syntaxes for pics in a section right at the top unless there s a reason not to talk
