If you want to display images that are larger than the Forum attachment limits (500x500 and 50K), you might want to consider one of these image hosting sites. Registration isn't required, and they're simple to use.
You should use one of these services instead of hotlinking and leeching from other cites; copy the image to your computer, and upload it to the free hosting site.
Be forwarned: they don't have gallery capabilities like the Cyburbia Gallery, and images may be deleted from them after a month or so. For photo series, you should stick to the Cyburbia Gallery.
