[18:40:43] <b_jonas>	 on Commons, can I search for an image with a certain checksum to see if it's already uploaded without trying to upload the image?
[18:41:29] <b_jonas>	 oh, maybe with [[Special:FileDuplicateSearch]] .. what kind of checksum does that want?
[18:41:31] <Reedy>	 through quarry/the replicas you could query for it...
[18:42:39] <Reedy>	 it would be SHA1 of the content in base-36
[18:44:22] <b_jonas>	 sha-1 in base-36, let me try to compute that. how do I view the checksum of a file to see if I'm computing that correctly?
[18:48:51] <b_jonas>	 ok I don't even know what base36 is. I'll give up for now and just try to upload the file (I needn't complete the upload, just start with the upload wizard), and get back to this if I ever need to do it with more or larger files
[18:50:36] <b_jonas>	 huh, these images don't exist yet
[18:50:46] <b_jonas>	 I'll have to upload them anyway then
[18:50:54] <b_jonas>	 I expected that they'd already be on Commons somewhere
[18:55:37] <b_jonas>	 oh great, in fact it's mixed, with some images from the set already on commons and others not
[18:56:34] <b_jonas>	 that will make it annoying to try to normalize filenames in a set when that happens
