I've been implementing the hosted version of text2png (*great* concept, btw - thank you!), and have encountered some strange behavior.
Replacing an <H1> tag within a <div>, the resulting png doesn't 'stay' where the original tag was -- it vertically aligns to the top, rather than respecting the padding and margin settings. This is only true in IE; Firefox behaves correctly.
In several other cases, where the replaced tag is immediately followed by an image, that following image disappears. This seems to occur in both FF and IE, although I haven't tested it thoroughly.
