do not load the document base. use getCodebase()
replace
image = getImage(getDocumentBase()
with
image = getImage(getCodeBase(), "think.jpg");
image = getImage(getDocumentBase()
with
image = getImage(getCodeBase(), "think.jpg");
cached page copy .. once again :(

Now use the MediaTracker to track whether this 'image' object is actually loaded. adding it to a media tracker and wait()-ing for it to load would probably do. This all you have to add after the "image = ...".
