Hi people

The company im working for are going to change to a new website in April (all being well). The web site is an ecommerce web site and doesnt have much textual content. At the moment on each of their gallery pages there is an image at the side with text in it, but not readable by google as its just an image (hope that made sense).
Im about to change these images for each gallery to have some relative text.
From an seo perspective i wasnt sure if it would be worth making these changes now if we are moving site in april. We will be keeping the same domain names but on a different server.

Thanks for your advice

Andy
