That's a feature, I think.

Nice.. bigger comment pictures than the original one shown above... O.o well.. whatever... at least it's not busting the design. So, forget whatever I said and ignore this topic...

I happened upon this “feature” some minutes ago while opening my own thread… HTML in BB and Blog posts? Image links resolved?
While I think freedom is fine, links should be displayed like in the entry posting and there should be a means of referencing images in comments/posts displaying the square or tiny preview.
