I use photobucket.
I plug my card into the card reader and my computer, open the finder window, which is where my card shows up. I opened a free acct with photobucket.com and upload my pics to there from the finder. The you have to scale each one down to size, it says resize, scroll your mouse to that and select for message board. That will get you to the right size. Click in "img code" and then paste it in your post here.
That made total sense didn't it???
BTW the finder part may be different cause I use a Mac.
