How do I resize a pic to something that isn't gigantic? I just posted something about a Twitter icon, the original pic is 267 pixels wide (maybe 2"wide), I resized it to 100 and then finished the post and the icon is the widest width possible. And why do some pics require alternate text and some don't?
