To recreate: 1 - Enable GoogleJackets 2 - Do a search on the OPAC 3 - Note that some covers are very large and show the cover page instead of the expected voer 4 - Inspect the element in the browser 5 - Note URL param zoom=5 6 - Change this to zoom=1 and note the cover looks right
I noticed this for the first time yesterday, which makes me think perhaps something changed on Google's end? the "zoom=5" is part of the response from Google's API, so it's not something we can easily change in our code. I did confirm that we are following Google's code suggestions (https://developers.google.com/books/docs/dynamic-links). I'm not sure where to go next on this one.
This appears to have been resolved on Google's end. Koha still sends the zoom=5 parameter but I'm not seeing any problems with the covers.
