Ok, I did it like you told me. Works pretty fine, but If I want to access a single page, I have to do that by page number. Is it possible to get a single page out of the tiff-file by using its original-filename? Or can I set some tags for each page, which I can use to "address" the different images in the tiff-file?

You cannot
load a page based on its original file name (before it was added as a TIFF page).
However, you can write tags or comments (original file name) to a TIF file
pages using the WriteTag Method or the WriteComment Method, and then search the
pages of the Multi-page file for the Tag/Comment (which is the original file name) using the ReadTag Method or ReadComment Method.

Some tags that you can use to write the description or name of original file are:

RasterCommentMetadataType.Description

RasterCommentMetadataType.NameOfDocument

RasterCommentMetadataType.NameOfPage

For more information, please refer to the .NET help file topics:

'ReadTag Method', 'ReadComment Method', 'WriteComment Method' and 'WriteTag Method'.
