hi, all,

I have a problem with image\_tag, the url it generates keeps adding ???  
at  
the tail.

e.g.  
src="/images/gicon.jpg?1153577588???"  
src="/images/gicon.jpg?1153577588???"

I’ve checked the source code of image\_tag, and couldn’t find any  
solution.  
The ???  
is appended to the “source” parameter before it goes to the real  
image\_tag  
code.

```
  def image_tag(source, options = {})
    puts source # already ????? here
    options.symbolize_keys!

    options[:src] = image_path(source)
    options[:alt] ||= File.basename (options[:src],

```

‘.\*’).split(’.’).first.capitalize

```
    if options[:size]
      options[:width], options[:height] = options[:size].split("x")
      options.delete :size
    end

    tag("img", options)
  end

```

I couldn’t debug further because I couldn’t find where the image\_tag was  
invoked.  
I think maybe it’s caused by encoding problem because I use utf8 as the  
default encoding for the project.

Anyone has a solution?

Best Regards,  
Zhenjian

Yes, leave it, it’s a feature. It will cause your user’s browser to  
reload the image whenever it changes and get it from the cache if no  
change was made. The parameter is the modification date.

yes, I know that the timestamp figure is the feature. I’m wondering how  
does  
those ??? (question signs) come out?  
When a page with many images is loaded, there are so many  
???  
(question signs) apear and make the page  
size really big. I want to find a way to get rid of these  
???  
(question signs).

Regards,  
Castor

That’s weird indeed, I’ve never come across this.

ok, I solved this by modifying the source code of image\_tag as follows

```
   new_source = image_path(source)
   new_source.gsub!(/\?\?+/,'') # strip the ending ???? here
   options[:src] = new_source
```

I plan to modify the source code of image\_tag to strip out those  
question  
signs if there weren’t any better solution.
