Thumbnail URL for Omeka pdfs #80

Closed adehner closed 7 years ago

adehner commented 7 years ago

All Omeka thumbnail images are image/jpg. And the file path for thumbnails of Omeka pdfs follows a reliable pattern: pdf = http://digitalcollections.lclark.edu/files/original/e758c06d94c8c245f97cb57b7148e4fc.pdf thumb = http://digitalcollections.lclark.edu/files/thumbnails/e758c06d94c8c245f97cb57b7148e4fc.jpg

Today Lewis & Clark contributed a set (http://harvester.orbiscascade.org/results?set=http%3A%2F%2Fdigitalcollections.lclark.edu%2Foai-pmh-repository%2Frequest%3Fverb%3DListRecords%26metadataPrefix%3Doai_dc%26set%3D47&model=primo) and the thumbnail URL in dc:hasVersion (for Primo) has a .pdf extension. The webResource for DPLA might as well.

Please update the file extension for thumbnails of Omeka pdfs to be .jpg

The XSLT was simply looking to replace 'tif' with 'jpg', but I have tightened up the expression to replace any file extension with 'jpg'. Note that I have no idea what happens in Omeka with sound or video files, and problems may occur (difficult to anticipate) if someone uploads a file that doesn't have an extension.

This is a good point, and one we should monitor. I'll see if I can find a couple of A/V examples to see what happens.
