I know what you mean. The image is already 36k. But it's the same logo on
all my pages, so once the reader has downloaded it, it's in the cache and
doesn't have to be downloaded again. And when I started using it, I got
compliments on the new logo and no complaints about longer loading time.
As you say, it's the only way you could do it, so one would just have to
weigh the advantages and disadvantages and see what the viewers prefer, more
images or faster loading.
I use a lot of photos on my site, but the viewers don't seem to mind the
downloading time. In fact, they often ask for more. On the home page,
however, I only use small images except for the logo.
