This concerns the 3 settings in the Image Bounds section of an album's Image settings.
When an album is created, the "Images" setting is set to the skin's default. For Tiger, this is 1000x800.
The user experiments with this setting, but eventually decides to revert to the default setting. There is no way to automatically select this.
Suggestion:
The drop-down list of suggested image sizes contains
2000x2000
1200x1200
1024x1024
etc.
Add the skin's default setting to the top of this list, so it becomes
1000x800 (default)
2000x2000
1200x1200
1024x1024
etc.
