OK, toe in the water.
I tried my first self-pub on Smashwords. It's an illustrated flash. I created the cover in Gimp. And it would not load. Funny, but if you read the directions, it works better.
The cover was too large. So I compressed the file and darned if it didn't load right away.
And I assigned it an ISBN. Wow. I have an official ISBN. Makes it feel more real somehow.
Then I got the message that I had failed the epub format conversion. That means the Apple Store won't carry it. So I followed the directions and plunked it into the Threepress epub validating site to find out what was wrong. I think it's because one of the illustrations was scanned as a PNG instead of a JPG. So I re-scanned, reinserted and reloaded.
I am presently 407 in the queue! I was 473 when it first loaded. Amazing. So many people producing work. Now I just need to be patient. Updates tomorrow.
