The following instructions are general recommendations for loading images into any Symbiota data portal, though specific requirements may differ from portal to portal depending on the project managers. Portals are typically used to publish web-ready images (e.g. JPGs). Archival images (e.g. TIF, DNG, RAW, etc) are best managed in a number of other software products specially designed for that purpose. JPGs should be web optimized with minor JPG compression applied. Field images are typically less than 1600 pixels wide and no more than 2M (<1M is ideal). Images should be cropped before loading to best highlight the subject matter. Some photographers prefer to crop images into a square format since they display best within the image thumbnail galleries. Specimen images are often larger (e.g. 4000px wide, 1-6M), but are typically linked to the portals using a batch processing workflow rather than loading via the user interface.
One must have a system login and the proper permission assignments before they will be able to load images through the user interface. If you do not yet have a login name, look in the site menu for a link to create a new account. Once you have an account, the next step is to contact a portal administrator to obtain the necessary permissions and instructions for uploading images. There should be a portal administrator contact link somewhere on the front page of the website.
There are three different categories of images that can be linked to a data portal. Use the descriptions below to determine which category best fits your material.
- Field images linked to taxon name only
- Image of a physical specimen held within an actively curated collection (or associated with Personal Specimen Management)
- Image voucher (field observation supported by an image)
Simple field images without specific locality information (e.g. lat/long coordinates) are linked only to the scientific name of the organism. These images can be viewed on the Species Profile Page along with other general information such as species descriptions, distribution maps, synonyms, common names, etc. Field images are uploaded and managed through the Species Profile Editing interface. Users with Species Profile editing permissions can submit an image by clicking on the editing symbol located in the upper right of any Species Profile page, or through the image submission links available on the sitemap page. Field images with specific locality details (e.g. coordinates) can be loaded as Image Vouchers (see below).
Species Profile Examples:
Images of physical specimens should be linked to their respective specimen record. Specimen images are available both from the Occurrence Details and the Species Profile page that is associated with the most recent determination. If the specimen identification is annotated, the identification of the image will be automatically adjusted. Note that if the image is given a sort order value of greater than 500, that image will be displayed on the Occurrence Details page but not on the Species Profile display. This is typically done for images of poor quality or due to aesthetic issues (e.g. road kills). Specimen images can be added via the user interface by clicking on the Image tab within the Occurrence Editor. See below for screen captures of the Occurrence Editor interface. See the Image Batch Loading page for workflows being used to load images in mass. A field image can be linked to a specimen record, but the image must be of the specific individual that was collected. Field images of a vouchered specimen are considered high valued images since species identifications can be verified or annotated years afterwards by close inspection of the physical specimen.

Field images with specific locality information can adequately serve as vouchers for field observations of many birds, mammals, and easy-to-identify plants. In some instances, they may actually be preferable, for instance if the organism is rare or the observer does not have the appropriate collecting permit. These images are similar to georeferenced specimen records in that they are searchable occurrence records that place a dot on the species distribution maps. There are, however, some taxonomic groups that typically require microscopic or chemical analysis for accurate identification (e.g. lichens, bryophytes, fungi). For such organisms, field images will have limited value. For this reason, some data portals might not allow the submission of observations without a physical specimen.
It is particularly important that images intended as vouchers for an observation be of high quality and clearly display diagnostic morphology of the organism.
As is the case with images of physical specimen, Image Vouchers are displayed on both the Occurrence Details and the Species Profile pages. Image-supported observation can be uploaded using the Observation Submission page. See links below for a screen capture of this page. Up to three images can be submitted for a single observation. Data fields required for an image to qualify as a voucher include: observer name, observation date, country, state, locality description, latitude, longitude, and at least one image. Contact your data portal administrator for information on whether observations are allowed and the necessary protocols for submitting an observation. Some portals require the review of a tutorial before one is authorized to submit observation.
