problem with rna secondary structure image in help docs

Hi lauren.

One more thing about the rna alignment image in the help - I presume you'll switch the current full width alignment for the image you've prepared for the NESCent newsletter ? When you do, remember to change the width/height in the img tag so it doesn't appear distorted, and could you change the image type from a png to a gif ?

The help publishing system isn't set up to cope with PNGs, mostly because they aren't as widely supported in web browsers, so we prefer to save all the images as GIFs optimised for web viewing with an indexed colour palette. (again, more guidelines that aren't actually written anywhere, yet!).

Cheers.
Jim.
