Well, since we *think* you are a pear (I'll let Angie chime in since she's the expert), a jacket that is a bit shorter would actually be a good thing, I think. This is what Angie says about lengths of tops in her pretty pear post:
"The length of your tops should always catch you on your hipbone. Avoid lengths that finish straight over your bottom. Avoid tops that stop just on or above your waist. This emphasizes your disproportionate top to bottom ratio.
Always wear slim fitting tops, sweaters, cardigans and button down shirts. Choose styles that define your waist and show off your torso. Boxy trapeze jackets continue to be all the rage and you can absolutely wear them (despite the fact that this goes against the rules) if you keep them cropped, fitted snugly at the shoulders and matched with a longer and slim layer underneath."
Since your waist is straight and rectangular, you will especially want to wear styles that give you the allusion of more definition in that area, I think.
The cropped J. Crew jacket might work, but it would depend on where it hits you. We'd have to see it on since you're tall and it might not hit you on the same place as it would someone like me (who's a shortie).
As to flipping the photos in Photobucket:
When you have your album open, there is a blue bar there that says, "Photobucket: My albums, group albums, etc." Underneath in the grey bar on the left, there is an option that says, "Edit images." When you mouse over it, a drop down menu appears with some options. The bottom option on the menu says, "More options." Click, "More options." It should let you choose which album you want to edit. If you only have one album, like me, it will automatically open the album and let you select a photo. When you mouse over a photo a button appears that says, "Select." Click on the photo you want to edit, and it will open a new window with options like crop, and then there are 2 buttons that have arrows that make a little circle. You click that and it will rotate the photo 90 degrees every time you click it. When you have the photo the way you want, you can either click "Save a copy" (blue button under the photo) or "Replace original" which will replace the photo in your album. Then you can post the direct link and the photo should appear right side up.
Sorry about the dense directions!
