To make things cleaner I would suggest you use the File's name itself when you save the image. I had an issue saving bulk images because they were not formated correctly. The images were saved like this:

#pic.jpg(1)
#pic.jpg(2)
#etc.

Thats why you should probably use the image name as the file name like this:

src = 'http://www.asite.com/pic.jpg'    
agent.get(src).save "#{folder}/#{File.basename(src)}"

File.basename takes the image url and just returns the the actual image name:

File.basename("http://www.asite.com/pic.jpg")
# returns the image name
pic.jpg
