When multiple classes with the same name are downloaded, they are merged into one folder

[LiamAttClarke]

For example, the following classes share the same name and thus all get downloaded to the same folder named 'cap'.

n02954340, cap
n02954938, cap
n02955065, cap

I suggest adding a folder name suffix such as cap_n02954340. This way the folder can still be sorted alphabetically and images don't get mixed together.
