@TBRC-Travis @jimk-bdrc I'm describing the issue just FYI. No action to take on your part, except perhaps buda-base/asset-manager#125 in the future. What happens is:

• the URL of the image requests the IIIF server to produce a 600px wide version of the image instead of the original, this means that the IIIF server must decode the JPG, resize it to fit the requested size, and reencode it
• because Java image processing is... bad... we can't extract the ICC profile of a decoded picture without a very big hit on performance (in Python this would be a non-issue)
• so we resort to a hack where we read at most the first x bytes of the original image, try to find the ICC profile in there, then go back to the beginning of the bytes (the reset function) and then decode the image
• this works when x is large enough to go to the end of the header where the ICC profile is
• in that case (because of the thumbnail), x wasn't large enough
• I've raised x from 40k to 60k, which solves this issue

There's an implicit request here to extract and store this information from inside audit tool. It's intriguing, and should be part of a general ingest step. I'll flesh this out in asset-manager#125
