Jun,
You're right, I was missing something. I see you can use insertEntry
to POST data. All 'entry' has to be is a well formed http request.
>From the documentation this isn't entirely clear as at first I thought
this was some sort of javascript specific object. I successfully
posted an image by:
picasaService.setHeaders("Content-type", 'multipart/related;
boundary="END_OF_PART"');
picasaService.insertEntry(POST_FEED_URL, data, handleUpload,
handleError);
Where data was simply the body of the post, including the jpeg data.
I'm glad to see that it works, but documentation could be clearer as
to what 'entry' is because from the API it seems as if you can only
create an 'entry' by using the constructor.
Thanks.
