Image Server Update - Oct 2017
Dear DEC Users - Software has been updated to Omero Server (version 5.4). You will be able to access the database with your we browser as before.

To upload new images you will need to download and install the latest version of OMERO.Insight (5.4.0).

Image Server Update - Apr 2017
Dear DEC Users - Software is currently being updated to Omero Server (version 5.3, announcement). During this period there will be numerous times that the image server will be unavailable. I apologise for any inconvenience. I will be sending an email to all users when installation and testing has been completed.

The collection scanned images are currently available as a test site with only a few sample images loaded. There is no unregistered user access available to the server. All users must apply for an account and agree to abide by our access and reuse conditions before being issued a user account. Individual user accounts currently only have access to specific folders. Access to other collection folders can be managed through user rights management.

2017 Test Image Link

This only in a trial, final database will vary from this draft structure.

  • Folder - Each embryo has own folder (with the original embryo name as it exists in your collection).
  • Project Details - CRL in mm and total number of slides available (from catalogue).
  • Tag - Plane of embryo section (Sagittal, Frontal, Transverse).


Locally uploaded image samples.


Selected slides form the Blechschmidt Collection are available for registered user access. Please advise me if you are unable to see the linked files below following log-in.

2016 Test Image Link

Note - You will need to login to access the original image through the links, images appearing on this current page are only screenshots.

Image Formats

The original decision was that scanned slides would be saved in JPGXR format as these are substantially smaller than the uncompressed format. Note that OMERO server will accept embryology images in a variety of formats, including uncompressed images, the problem will be the overall size of the database would be unmanageable.

Following collection scanning, each collection manager should also hold an uncompressed archive of their own images. Should you require images of this quality/resolution, please contact the original collection managers.


The Axioskan slide scanner generates images in the CZI file format that was developed by ZEISS to specifically meet the requirements of imaging in microscopy. This is an excellent uncompressed research image format, but generates images that would be far too large for easy access on the DEC image database.


The Axioskan slide scanner software can also save or convert images into the JPG XR format. Note that the image file extension will still be shown as CZI, but this will be a "compressed" file. This format was selected as it has not licensing requirements, generates smaller good quality images, and the scanner can readily batch generate this format.

The JPG XR file format is a still-image compression standard and format for continuous tone photographic images, based on technology originally developed and patented by Microsoft under the name HD Photo (formerly Windows Media Photo). It supports both lossy and lossless compression, and is the preferred image format for Ecma-388 Open XML Paper Specification documents (Wikipedia). This file format is also an International Organization for Standardization ISO/IEC TR 29199-1:2011.

There are several research conversion programs, including Fiji (ImageJ), that can both read and generate this image format.

Additional non-research programs are available for image conversion into this form (Google search JPGXR conversion).

Caution - Users should be extremely careful when downloading software from the internet and should contact their local IT managers and use anti-virus software to screen before opening, installing or running any such downloaded program.

JPEG 2000

OMERO Bioformats should also be compatible with the [ JPEG200 image format, though we have had some initial issues with this on the database. For example the image will upload to the database, but will not be able to generate the thumbnail or process the required pyramid.

  • Problem - One Image 3 formats only the JPG version has generated a thumbnail image, both the TIF and J2K versions show that they are still "generating a pyramid".
  • Problem - J2K image similar problem.
  • OK - JPF image photograph not a scanner image uploaded and displayed without a problem. (see JPF extension)

JPEG 2000 is both a codec and a file format and the standard is in many parts.

  • Part 1 giving (mostly) codec information (how to compress/decompress image data), with a container file format annex (JP2).
  • Part 2 gives many extensions, and a more comprehensive container format (JPX).
