@balloni: images are not preloaded. So they are loaded when needed. Images in logs should be stored in Locus/cache/images directory and images in "Images" tab are cached automatically by web browser in internal memory (where is limit for cache around 10MB)
And really no need to sorry about waypoint. It's my problem that explanation is not clear!
@ta-ka: thanks. I received one report on bugsense, but it will need some more testing later. Anyway what application are you using for a taking photo/video? I'm on 99% sure, that duplicates are problem of this app, not Locus. Because Locus only say to system "Call app that store image/video to this X file", and that's all. When this task is done, system call back to Locus "OK, done" in case you took a photo or "Sorry canceled" if you canceled it.
