XML as database for CD Gallery???

[SStory]

I am creating a CD that will have various product images. I need more
information on these JPG's so I will need some sort of data on each of them.
I will also need to be able to find these images by keywords, title,
subject, etc....sort of a gallery.

I was considering trying to use XML to avoid using any database. It will be
a fixed set of data, except that from time to time additional items may be
added--via internet download.

What is the group opinion on doing something like this? Would XML be a good
solution?
Too difficult and not worth the trouble? Too verbose? I figure 5000-10000
images max--but no bigger than 300x 300pix.

I am fairly new to XML, but from what I read it appears that the XDocument
class might be the one to go with for something like this. I have also
considered that maybe it should somehow be in XML but then read into a
dataset to be manipulated sort of like a database.

All opinions encouraged...

If the general agreement is that XML would be a good solution, please
provide some of the best resources for doing what I need to do...

Thanks,

Shane
