A) Anchor text links
For a while I've been trying to argue that form and content aren't truly separate in html composition because it's nothing like paper. How could I have forgotten one of the best ways to prove that: Text anchors.
If being able to link within the page is an integral part of how the page will "work," plan ahead for that please. However, if you're composing in html right now and you try to add them at this stage the "links"may change as the file's name or position changes. Fixing it shouldn't be too difficult, though.
B)gif. problem solved?
I've found that saving .gifs with Fireworks makes for higher-quality .gifs. Adobe products could likely do even better. Just something to keep in mind, that's all.
