Something to mention here is that the images should also be appropriate for this Forum. They should not be in bad taste or have potential copyright infringement issues.
Also, sizewise it is more pleasant if pictures fit in the window without scrolling from side to side. If they stay at/under 550 pixels wide that is not an issue. File size can be a concern for those still on slower dial-up connections. Files over 100k in size can slow down page loading considerably, and they do add up.
