I don't know about posting pics cause I never do; maybe they were too big. In any case, you shouldn't post the whole pattern here - that would be a copyright issue. You probably can link to the pattern thru interweave.com. They usually show patterns that are in different issues. Another choice is if you are a member of www.ravelry.com, you can probably find a link to the project there.
In any case, tell us the name of the design. Probably many of us will own the magazine/issue.
Just an idea, if you just need to make it one or 2 sizes smaller, look at the sizes listed in the pattern. If the smallest size is cast on 10, then the next size up is cast on 15, then the next size is cast on 20, etc, maybe you can figure out how to size it down by looking at the math between the sizes. A lot depends on the pattern and how complicated it is.
