Today i've discovered that my attachment feature is far from perfect - any big images just run off the page for miles!
I'm working on trying to get them to resize automatically, but meanwhile any attachments to posts will be displayed as a link, where you can view the image on a separate page.
Alternatively, you can still link to photobucket (or anywhere else) with image (Img) tags, and they will appear imbedded in the post...
Sorry for any inconvenience
