I have images stored in a database. I now need to read those images from  
the database and store to files (using ActiveRecord in a system where  
$KCODE = ‘u’; require ‘jcode’ is used (if that matters…)).

I’ve tried a couple of approaches but it’s only giving me destroyed  
images (when served to a browser using webrick they look perfectly  
alright).

I’ve tried:

```
 str_bin = ""
 self.data.each_byte do |b|
   str_bin << b
 end
 File.open("public/published/#{self.name}", "w") do |file|
   file.print str_bin
 end

```

and

```
 File.open("public/published/#{self.name}", "w") do |file|
   file.syswrite self.data
 end

```

and

```
 File.open("public/published/#{self.name}", "w") do |file|
   file.print self.data
 end

```

All with the exact same result.

I suppose there must be a simple way to solve this?

Does using “wb” instead of “w” in File.open make a difference?

Yep, that worked. Thank you very much.
