Hi Tena

The following assumes you have only images in your collection.

My suggestion would be to use the Librarian Interface, Drag the images
themselves into the collection. Don't worry at this stage about creating
html pages around the images - you can do that later if you need to.
Use the Enrich pane to add metadata to the images.

In the design pane go to document plugins. remove HTMLPlug (this blocks
images) and add ImagePlug. You may want to create thumbnails - set
thumbnailsize to enable this. If you create thumbnails they get shown in
any browse/search result lists. It probably pays to remove the other
unnecessary plugins - some others may block images too.

In Search Indexes, you may want to change the indexes to use metadata
you have assigned. the document text index will be useless as images
have no text.

In Browsing Classifiers, also change the classifiers to use metadata you
have assigned, rather than extracted metadata which is generally not
veery useful for images.

Now build the collection and preview. If no documents are considered for
processing check the image file extensions against the process
expression for image plug (configure plugin) and remove any unnecessary
plugins.

if you have created thumbnails, then they should show up in browse lists.
When you click on a document you will see "this document has no text"
instead of the image.
Go to design pane in GLI, select Format Features, and add in a
DocumentText format statement.

A very simple example is:

[dc.Title]
<br>
<img src=/gsdl/collect/gsarch/index/assoc/[assocfilepath]/[Image]>

this displays the dc.Title metadata then the image.

Hopefully you can get this far with your collection. And then you can
design it properly by working with the indexes/classifiers and format
statements.

Hope this helps,
Katherine Don
