Answer 1

I'm assuming you have everything working with paperclip, such that you have uploaded an image and now the proc is just not working.

It should work. Try not putting the size in an array.

You are doing this

sizes = { :thumb => ["100x100"] }

But I have it where I'm not putting the size in an arry

sizes = { :thumb => "100x100" }

Give that a try :)
