The second photo was a pretty good size for uploads. The limits on attachments are a little strict, intentionally, as a precaution against people filling up my server or uploading images bigger than the screen.
You can include bigger pictures by linking them off of a site like flickr or photobucket, and using the forum's "img" tags/button. I know it's a little weird when you're new to forums, but the "bbcode" way of doing it is pretty standard on most forums, so you really only need to learn it once, which helps.
Great collection! It looks pretty diverse, which is always cool. My sword collection has been all over the place as far as styles go. I'm starting to narrow it now.
