I finally got envious of the visually interesting blogs other people have and redecorated, but when I went to see how my comic After Dark fared in the transition, I realized that half of the images were gone.
This is not a Weebly fault, but rather a Photobucket fault. When I first put After Dark on Weebly, it wouldn't display the uploaded images in full size, and since they're comic panels with word balloons, that was kind of important. My work-around was to upload the images into a private album on Photobucket, then use Weebly's embed code feature.
The album is still on Photobucket, it still contains over a hundred comic panels, and there's no logic behind the missing images - they are no more or less offensive to Photobucket standards than the remaining images. I have no idea when the images disappeared.
Which led me to the realization that no one had noticed. Making the fix very easy.
Meh, the novel was better, anyway.
