There are three different sizes of each image in a gallery, a full size version (up to 2 Mb) and two resized versions (a small, thumbnail version and an intermediate version). Clicking on a thumbnail will display the intermediate version, clicking once more on that image will show the full size version, which normally does not fit to the screen but requires scrolling to view the entire image. You can also choose between the intermediate and the full size version by clicking on the image dimension (in pixels) for either size below each thumbnail.

In all plant galleries the caption below each image refers to the scientific (Latin) name of the species in question. By moving the mouse cursor into an image a rectangular box will pop up containing further information about that very image, the file name, the vernacular name (in Swedish and/or English) if existing, the capture date and the locality, sometimes even the habitat, which is always the case for lichens. Most lichen photos are furthermore close-ups with a magnification ratio ranging from 2:1 to 1:8 and then the calculated actual image width is mostly part of the popup information.

If the name of a species is written in red a commentary field will be displayed in a rectangular popup box when moving the mouse cursor into the name. These comments are almost exclusively used in the Lichen Gallery and contain information of various nature, mainly intended to verify the correct usage of the name.

The fastest way to find an image of a specific plant is to use the Index for each Gallery instead of selecting an album or entering a gallery from the top level. On the Index Page you will find the names of all depicted plants with the number of photos for each plant in brackets. By clicking the name you are looking for, you will be directed to the first page with thumbnails of the requested species. You then have the option between the intermediate and the full size version. The first version loads fast and has mostly enough detail for identification, while the latter version may take some time to load and should be clicked only if a more critical examination is desired.

The thumbnails in an album are arranged in alphabetical order with 8 images on each page. For an often depicted species they can consequently span over more than one page. If necessary just click the Next Page Arrow (>>) or the Previous Page Arrow (<<). From any album page you can go to any level of a gallery or return to Index Page, Galleries Page or Home Page by means of the menu bar at the very top or at the very bottom of each page.

The viewing and searching capabilities should be very good with a late version browser like Internet Explorer 6.0 or later and a high-speed (broadband) connection. However if you have a dial-up (modem) connection (especially a slow one), be prepared it may take some time to browse a gallery. Our old server was in the first week of November 2008 replaced by a new more powerful one and should not constitute a bottleneck.

Our image galleries have been created and are managed by a web application (somewhat modified) Gallery (version 1.4), which is free and available in over 30 languages. As the Gallery Project is an Open Source Project (written in PHP) you are allowed to modify the code to suit your own needs. Just as an illustration part of the PHP-code has been rewritten in order to implement the popup information boxes pertaining to our images. They are generated by means of a Javascript utility, called overLIB, which is freely downloadable.
