That wasn't me last time :8} but you need to click on Album Settings to un-check the box that auto-rotates images on upload.
Also have a look at Upload Options (a small link at the top of the page after clicking Album Settings) and make sure the re-sizing setting is allowing for the width of your images.
They also recently introduced the beta version of the site and there were some issues with the current version (I couldn't upload at all for a while except on the beta site, but that doesn't have the options I want as yet so switched back to the original), but if the above doesn't work, you could always test the beta version and see if that resolves the isuues you're having.
I also use Image Shack occasionally, but it's a little harder to keep images well-organised and getting direct links for lots of different images can be a PITA, so I usually just use that for something I want to post as a one-off and when I don't want it to be linked to PB.
