There's a restriction on the forum that limits photos to no more than 600 pixels in either direction, so when you resize, the thing is to get it as close to those dimensions as you can.
The alternative is to host it on another photo-sharing platform where you can usually post larger and get links to post the images in a forum, but if you post massive photos that way, those of us on relatively slow connections probably won't wait for them to download. So if you host externally, posting the 1024 x something size picture is ideal. Most photo hosting sites allow you to upload in full size, but then post a smaller version on the forum - this is great because the forum page loads quickly, but those who need to see in full resolution can usually just click on the photo.
The down side of external hosting sites is that they've recently had a habit of going from free to charging, without much warning, and then taking your photos off-line if you decide not to pay (like Photobucket). Or shutting down completely (like TinyPic). So there are lots of forum threads rendered useless because all the images have disappeared.
For me, the forum hosted images are the best solution, because you know they're not going to disappear any time soon. The size limit doesn't usually make a great deal of difference.
