  • Milestone changed from 5.0.1 to 5.0.2

This is mainly due to the way we handle "large image" i.e. images are big but not big enough to qualify for pyramid generation.
The strategy needs to be reviewed since it is becoming an increasing issue (cf. notes taken during Canada/US) road trip. 2 options

  • Lower the threshold for pyramid generation (1kx1k)
  • Handle big images display in client.

The first option will be the quickest for new files, but we will need a script to handle file already imported
second option implies that the work needs to be implemented in all the clients

Note something we can tackle in 5.0.1, pushing to 5.0.2 for discussion asap.
