follow-up for posterity: i couldn't find a way around this, though i suspect it might have worked if i kept access to the underlying http object and had it add the imgmax=d as POST data rather than GET data. honestly figuring out this API is more frustrating than it ought to be.
instead I just iterated over the local copy of each file (i have a separate bone or two to pick with the mac osx photo uploader, by the way) and used the local metadata to update the photo.summary.text and save each photo (and manually restored the few photos that had been clobbered by the downsampled image). I don't believe updating the summary text actually fixes the in-image IPTC metadata, but this falls under "good enough". next, i'll see about splicing in the geo data from my gpx data :) On Sunday, January 3, 2016 at 8:26:58 PM UTC-8, Sean Finney wrote: > > Hi everyone, > > OK, long story short, I uploaded about 800 full resolution images with the > wrong IPTC tag set, so the images do not show up with captions.
