Web Gallery Creator Custom HTML templates

HTML templates approach in Gena

When Gena creates html pages for Index or Image it actually uses special html template files. The template file is a normal html file with Custom Gena tags – special reserved strings recognizable by Gena’s syntax analyzer. Gena substitutes custom tags with appropriate strings producing target html file. Suppose Gena creates Image html page for picture “image00.jpg” from html template like this:

<IMG SRC=%genaImageName% WIDTH=%genaImageWidth% HEIGHT=%genaImageHeight% BORDER=0>

%genaImageName%, %genaImageWidth%, %genaImageHeight% – are custom tags. Gena will substitute these tags with the image name (“image00.jpg”) , image width and height and resulting html file will look like this:

<IMG SRC="image00.jpg" WIDTH=800 HEIGHT=600 BORDER=0>

During the gallery creation Gena use three templates:

  • Index template – for all index pages
  • Image template – for all image pages
  • Thumbnail (Item) template – for all thumbnails in all index pages

The Index page contains special tag %genaIndexTable%. Gena will substitute this tag with the entire index table (i.e. all thumbnails). For each individual thumbnail in the table Gena will use Thumbnail template to generate actual html code for each table cell.

See full list of custom tags here.

By default, Gena uses internal templates (you’ll see “DEFAULT” in the Advanced settings/ Template section). You can change any default template to a custom template file (or edit the default file and save it as a custom file).

Template Editor

The Template Editor is just a simple text editor with the “Insert Tag” button to insert Custom Gena Tags into a template file.
You can also “Save” the current template to a file and “Save as” a new file. When you editing the default template, the “Save” button is not available to protect internal template files, but you can save a modified default template to another file and use this new file.

You can use the Template Editor menu to load template files into the editor, reload last opened file and do basic editing (cut/copy/paste/delete).


Custom Gena tags

You can find all custom tags in the table below. The first column contains the tag name (without trailing/leading percents); the second column contains a short description of the tag. The third column shows example of what a tag could be expanded to. And last column shows where this particular tag can be used – in Thumbnail template (Item), Index template (Index) or Image Template (Image). Many tags can be used in more than one template file.

(*) Text templates are “Second level tags”, i.e. they can contain another tags and they are parsed in two steps. Text templates are specified in Advanced Options and they can include “Text Strings”, other Tags, font size/color, etc.
Let’s suppose the user typed in the Gallery Title “My vacation” (i.e. Text String tag %genaGalleryTitle% will expand into “My vacation”). The user also specified the following in the “Advanced Options”/”Text settings for “Title”:
– “<H2>%genaGalleryTitle% . %genaImagesTotal% images.<H2>”
– Font size:2
– Color: Black.
In that case %genaTitleText% will expand into “<font color=#000000 size=2><H2>My vacation. 3 images.</H2></font>”.
By default, Index/Image titles (%genaTitleText%, %genaImageTitleText%) contain %genaGalleryTitle%, Image description template %genaImageText% contains %genaLongCaption% , thumbnail description template %genaThumbTitle% contains %genaShortCaption%.

(**) Actual set of navigation links depends on the NavigationType for the image/index page.
E.g. if the navigation type is “Top”, genaLeftArrows, genaRightArrows, genaDownArrows are all empty strings and genaUpperArrows contains all enabled navigation links.


EXIF tags

Gena also supports a group of tags to display an information from EXIF image data. You can use these tags in the Item/Image templates to display desired EXIF information.

exifCameraMake Camera Make
exifCameraModel Camera Model
exifDateTime Date and Time
exifWidth Image width
exifHeight Image height
exifOrientation Orientation
exifFlashUsed “Flash”/”No Flash”

IPTC tags

Gena also supports a group of tags to display an IPTC data from the image. You can use these tags in the Item/Image templates to display desired IPTC information.

Custom Text Tags

Gena provides two predefined tags for image descriptions – short caption and long caption. By default this tags are used for thumbnail and image captions respectively. But sometimes two textual strings for each image are not enough and gallery design demands more information about each image. One example is a gallery with a shopping cart, which requires several attributes for each product (image) – short description for catalog with thumbnails, long description for product page, item price and ID for shopping cart engine, etc. In that case you can create a template for your gallery using multiple custom texts, adding new tag for each attribute of the image.

Custom tags are created in the picture bar (at the bottom of the main window) when you choose “Add New Custom Text” in the text type selector. Custom tags syntax is %genaCustom 1%, “%genaCustom 2%, etc. up to total number of custom tags created in the workspace. (Gena supports up to 32 custom tags).
