The camera I'm using is exploding the images to a certain size. Is there either a slideshow feature or a way to resize the image somehow using parameter for the IMG tag?
I think this question may be helpful about photobucket: Do you like the recent changes to photobucket? I am having to double click the image to get the image code for posting now. Before I could get it right below my small pictures without clicking on the image.You can always get a photobucket account and when you upload it there it will resize it for you.
Or, like GKYLEKING said, open it in Microsoft Paint. In older versions use Image>stretch/skew, and put in something around 25%. In newer versions (2007 or newer) you can just hit resize on the main page. Remember to save as a copy in case you ever need the original for printing.
