I haven't had a problem with Photobucket so far. This image is just as uploaded it as 341x500 pixels. It is 72 DPI though, I see you are using 300DPI. Save a copy of the original and convert it to 72-100DPI which is pretty good for just showing on the web. The light looks good, Is it cropped? if so how much. i would like to see a closer shot to see the detail on the rocks if you are willing to try using the 72DPI should give you a nice size image.
