The translate page points to the style sheets on the ET server under normal circumstances. That way new styles are reflected in the output if they are defined. Checking the box should link instead to the local versions I downloaded to the content directory. Might be useful if ET is unaccessable and you still wish to do some translations. Or if you wish to define some other styles locally. In fact, now that I think of it, it may not be completely correctly implemented...

The image fixer was implemented before the ET style sheets specified a maximum image width. It was to force a max width in the case where an overlarge image was posted. I removed it... In fact, I cannot find the bit that sticks that in the menu in my files. But, still, there it is. Hmm, strange. I'll keep looking!
