    I can't quite see why this image: from the commons gallery http://commons.wikimedia.org/wiki/Trichechus_inunguis isn't being harvested (the other two pictures in the gallery have been). It seems to be tagged with {{PD-self}}, which should be enough, I would have thought

    @Yan Wong: Patrick has been away but now he's back and might want to talk about this -- perhaps move discussion to http://eol.org/forums?

    @Cyndy Parr: Thanks. I've had a look at the codebase on github - I guess I could probably figure out a patch, but best left to people who really know how the system works (seems like Patrick Leary from looking at the code :). Shout if you want me to have a go.

    @Yan Wong: Thanks for explaining that the rotation is saved in the EXIF metadata. As Katja says, we'll put in the request. I'm a bit more hopeful -- this doesn't seem like it would be too hard to address.

    @Katja Schulz: Yes, of course. I can see this is quite low priority. Lots of other important stuff to do. Good luck!

    @Yan Wong: Thanks for the suggestion. I'll add it to our list of feature request, but I wouldn't hold out much hope for this to get addressed anytime soon. There are too many more urgent requests in the pipeline.

    Yan Wong commented on "EOL Discussion Group":

    @Katja Schulz: Thanks. I've just checked and the original images were rotated correctly, but the rotation was done by setting the EXIF rotation metadata (see e.g. http://www.daveperrett.com/articles/2012/07/28/exif-orientation-handling-is-a-ghetto/). This metadata seems to be stripped out by EoL, not by Flickr. You can check because the original image on Flickr contains the correct rotation information (download if from http://farm4.staticflickr.com/3757/8812291168_ce56ecf228_o.jpg and have a look). I can re-upload my images on Flickr so that they are rotated without using the EXIF rotation hints, but I guess other people might get bitten by this too, as many cameras seem to use this way of rotating pictures. Maybe it should be on the (long) to-do list to get the image import routines in EoL to save a fully rotated image (as specified in the metadata) as the local EoL copy?

    Katja Schulz commented on "EOL Discussion Group":

    @Yan Wong: The original images you uploaded were probably incorrectly rotated, and they got auto-rotated by Flickr. However, we download the originals from Flickr, so we get the incorrectly rotated ones. Unfortunately we don't have a solution for this problem right now, so we have to ask our contributors to upload correctly rotated images to Flickr.

    Yan Wong commented on "EOL Discussion Group":

    I've just tried posting some old pictures of mine to the EoL Flickr group. On Flickr the images appear in the correct orientation, but on EoL the imported images are sometimes rotated incorrectly. See for instance http://www.flickr.com/photos/96340474@N07/8812291168/ and its imported version http://eol.org/data_objects/24774483 I guess this should be a relatively simple bug to iron out. My suspicion is that it to do with the way image rotation is stored in jpegs by Mac OS X preview, but it could be a flickr auto-rotation thing.

    Thanks for the suggestions. I'll look into it further, and hopefully the results will be worth it.

    @Roderic Page: People would be pretty good at the coarse matching (shrimp-like, bird, mold, flower) so I'm not sure it is helpful to have computer vision do that part. Definitely an area for research.

    Roderic Page commented on "EOL API Discussion Group":

    If EOL already has the image then it should be straightforward to create a service to locate it (just match a hash of the image file). Google Images supports searching for images (go to http://www.google.co.uk/imghp and click on the camera icon in the search box). I've searched for EOL images and Google finds them (for example, chose an image from EOL, download it to your computer, then upload it to Google images and search for it). This answers the question "is this particular image in EOL?"). This question is obviously limited as it requires EOL to already have the image, but you could imagine that as more and more images end up in EOL (e.g., via Flicker and iNaturalist, and other contributors) the chances that an image you find on the web already exists in EOL will start to rise.

    The problem of finding an image "like" one you have is harder. Google supports this query as well, but seems to rely on matching images with similar distribution of colours, and so doesn't work terribly well. There are some useful posts on Stackoverflow about the general problem, e.g. http://stackoverflow.com/questions/843972/image-comparison-fast-algorithm and http://stackoverflow.com/questions/75891/algorithm-for-finding-similar-images.

    It strikes me that another way to tackle this question is to ask it in an other way, namely "what images would an organism generate if photographed?" For example, take a 3D model of an animal (the BBC has some which could be used as starting points), generate 2D photos of different aspects, then use something like template matching to try and classify images. Even a coarse classification (this matches a shrimp) might be a start.

    @Jonathan Ray: Ah, we once had a Google Summer of Code student working on a way to do image finding using an image and it is a VERY VERY hard problem. LeafSnap.com is an app that does this for North American tree leaves; it is pretty specialized.

    Their wouldn't be any other data being sent, it would be based on I don't know what I'm looking at so find it for me approach. I thought it would be a long shot, but thought I'd ask.

    EOL doesn't have any image matching algorithm, if that is what you are after. Can you say more about data that might go with the image? Do you have any source or taxonomic information?
