Mental note:
It's supposed to be "You can't see your profile picture?" Not "You can't see you're profile picture?" Derp-fail on my part!
Actual comment:
My chief thought right now is that pictures on your web-browser are blocked for whatever reason? I mean, if you're using a computer that is not yours, or have administrator access to, pictures from certain sites might be blocked. I don't know your situation, however.
*Edit: As long as you mentioned your blog, I took a glance at it. I saw the text "<DELETED>", "<IMAGE DELETED>", or whatever. That's... not supposed to be there, is it?
*Edit 2: Out of curiosity, I checked out rpgmakerweb. I can see you profile picture there as well. Which makes me lean on the whole "images blocked on your end" answer all the more.
