Sorry, I forgot this important command:

CheckOnly *.jpg *.png *.gif



Without this command indexer downloads the images

but then it does not know what to do with this

context, so it assigns status "415 Unsupported Media Type"

to them.

There is no such feature.

Yes, this is possible. 

In this case you need to remove the above "CheckOnly" command,

so indexer will start downloading the images again.

Then you need to feed them to some external program

which will extract meta data from the image files

and print them in HTML format putting image meta data

in HTML meta tags.



indexer.conf commands:



Section meta.imagetag1 30 128 

Section meta.imagetag2 30 128 



Mime image/gif text/html "/path/to/gif2html $1"

Mime image/jpg text/html "/path/to/jpg2html $1"

Mime image/png text/html "/path/to/png2html $1"
