[Dspace-general] Thumbnails and duplicate image filenames

[Clive Gould]

Hi

I've been uploading some images recently into DSpace and have encountered
a problem with the thumbnail images, where two images are different but
have an identical filename. This is particularly a problem with images
uploaded from a digital camera on a number of separate occasions.

In such a case the items are correctly uploaded and independently
displayed in DSpace but the thumbnail for each image has the same name and
hence both images have an identical thumbnail displayed.

An example is shown here:

An exerpt from running the filter-media script illustrates the problem:

Format: 'image/png' Filtering Class: 'org.dspace.app.mediafilter.JPEGFilter'
FILTERED: bitstream 214 and created 'Picture1.jpg.jpg'
SKIPPED: bitstream 213 because 'Picture1.jpg.jpg' already exists

This implies that if a number of images from a digital camera are uploaded
and if any have identical filenames then the thumbnails will not display
correctly.

I have a memeber of our media team wishing to upload some images - do I
need to make sure he doesn't use any image filenames which are already
in use? As the image collection grows this could easily become an
administrative burden.

Has anyone found a way round this problem?

Thanks very much
