Resaved the exif data, same result, the full error message (hard to copy with an iPhone) is
The URL is odd - this has 18.104.22.168/bmi/ Pretended to the actual URL in the IMG tags. Don't know if this is normal for the internals of AMASS.
No, that is not related to Amass code in any way. Add to gallery command passes img src from DOM to ajax. Check html source, what is the url there? Something adds that for you there (router?).
