Coldforged has an entry title image replacement plugin that lets you have titles like mine (done previously) that also has word-wrapping. I think I saw an approach somewhere (was it b2evo?) that actually broke each word into a separate image. For me the length limitation isn’t a limitation as much as a sanity check, if I’m writing titles so long it breaks my site I should probably shorten up a bit. I’ve also found caching isn’t worth it, every title here has been completely dynamic for about a year now.
