I would have a few suggestions to improve the usage of the galleries (and I do hope I haven’t overlooked this is possible already).
Editing/Order of images in a gallery
If I want to change the order of images I have to
either click the up/down arrow until the image has reached the final position or
I can drag an image and move it up/down. This works basically but scrolling in the relatively small “Insert/Edit Gallery” window (where you can add images) doesn’t work too smooth.
An easier drag and drop approach would be good.
In an external image editing tool I’m used to add all the image caption data and then exporting it for further usage. Unfortunately I didn’t find a way to have the gallery recognize and use the IPTC caption data. I think that would be useful in general.
Protect against “Right-Click”
I (personally) would like to have the possibility of a protect against download rsp against “Right-Click” so that people can not simply download images.
