You can store anything you like in Cassandra. The type of data is not
relevant as there are no types in Cassandra, they all get stored as byte
arrays. The only relevant limit is a column value cannot exceed 2GB (see
http://wiki.apache.org/cassandra/CassandraLimitations).

In terms of how: you just write the data like any other field. If you are
new to NOSQL I would go and look at the Hector API and examples:

Look at  http://goo.gl/S2E3C http://goo.gl/S2E3C 

It really depends on your workload. With heavy workloads cassandra is not
the right solution to store images and other large objects. You will get hit
by compactions taking longer, slow reads, disk space wastage since currently
you need 50% of unused disk space. But if you have low throughput
requirements then you can probably go with Cassandra. It's best to run some
stress test with bigger column size and projected traffic for next several
years.
