Folks at GoDaddy tell me Coffee Cup HTML Editor is not totally compatible with Firefox and Opera. I designed my website with Coffee Cup. Jpegs on my site appear perfectly well with Internet Explorer, but often will not appear either with Firefox or Opera.
Why is this and can it be corrected?

Can you please post the link to your site so we can check what may be happening? Text editors are compatible with all browsers. Any image problems can be corrected. We just need to find the cause.

Probably didn't find CoffeeCup HTML Editor in his "scriptbook" that guides him to "help" customers. There have been MANY sites made with CoffeeCup HTML Editor over the years, and they work with all browsers (yes, some browsers need special workarounds, but that's not a CCHTMLE issue). As Cary said, post a link and someone here can look into it and assist.

I maintain a site on GoDaddy using the HTML Editor, and it works great.

With a link, there are many folks here that are willing to look and provide wonderful help.
