Mark,
Do you have a website? If you don't you can usually get some space for free with your isp...check with them. You should upload the images to your website first. Design a page for pics with smaller thumbnails that link to larger pics. This allows faster loading for slower connections.
Here's an example of how I have posted some of mine: Home Theater Pictures
I don't believe you can post pics on the forum larger than a few text lines.
