Hey UC,
I've finally got a chance to play around a bit and it looks good. I have ran into a couple wacky issues though.
1. Seems to be a bug. Adding images to the default album actually uploads them to the root assets folder instead of the new folder image gallery creates for them:
a. Create a new imagegallery page
b. Save the page
c. Go straight to the Photos tab and upload some images
d. Save the page
e. Navigate away from the page, for instance click on the Files & Images tab to see that the files were uploaded to the Assets folder rather than assets/image-gallery/etc/etc/
f. Return to the imagegallery page and go to the photos tab, all the images will now be a default image icon showing that it couldn't find the images.
This didn't happen when I created a second album and specifically named it. The default album folder is being properly created in the asset manager, it just isn't being used.
2. This is just a usability quirk. When adding images to a new album, the default album may be listed by default in the upload dialog boxes:
a. Create a new album for a gallery page (make sure there are at least 2 albums)
b. In the photo tab select your new album for uploading to, notice the button says "Add images to {your new album's name}"
c. Upload at least one image
d. When the edit window appears to name and caption, the album selection will be on default album. If you save without changing it the image will be moved from where you intended to save it to the default album folder.
With this one it is a bit counter-intuitive that I've gone to all the trouble to select a specific album, just to have to select it again for each picture I've uploaded in the edit phase. I don't know how much of a challenge it might be, but it would be ideal if that selection followed the album selection in the main photo tab.
