It’s a bug – thanks for the report. Please install version 1.2.6 using sudo gem install fastimage

Hi, I’ve tried this code:

FastImage.size(“http://www.thanhnien.com.vn/News/Picture201001/lop10.jpg”)
=> nil

I can load the image by FireFox, and see its size as 250×188. What’s the problem?

Stephen: As of right now I have open-uri just download the whole file. It was a quick hack since I mostly use the lib for local files. I’ll check out fastimage.

Jason: yes, I’ll add that feature

Michael: that uses open-uri to fetch the url – I wonder if it fetches only the minimum necessary to get the size. I’ll test it.

Another project you may be interested in is http://github.com/andersonbrandon/ruby-imagespec

It gives you the dimensions and content-type of PNG, GIF, JPG, and SWF (Flash movies). You can pass to it a URL, file handle, or a string containing the path to a file.

Nice work!

Would it possible to use a more general URL? So local files are treated in the same way?
