Uploading multiple images with same image name doesn't work

[take]

Ideal behavior

Maybe an automatical image name update something omg.png, omg.png to omg.png, omg_2.png?

Current behavior

DB column value ends up like ["omg.png", "omg.png"], but only the first image is actually uploaded.
Same thing happens when I use the unique filename strategy(same filename but only 1 image uploaded).

BTW I found out that this happens when using iPhone to upload images :)

multiple file upload feature was added in #1481

I guess we can avoid this problem if we change store_dir from

"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"

to

"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}/#{INDEX OF THE FILE}/"

This is definitely an issue that I want to look into closely.

#2029 might be a duplicate of this, or at least a similar problem? @take any more info you can provide?
