Changing the font size might help. I looked at the link you typed up, but where would I type that? Would I have to modify some core Codeigniter function? If so, isn't that bad if you want to upgrade later.

Sure, you should change it but not the one in System folder, you should create a new one (a new helper file inside application folder)

Go here:

Below this subtitle you will find how you can achieve that.
"Extending" Helpers

This would keep your "core helper" as they are and will not be a problem for a future upgrade.


About the refreshing thing, I have just made the same thing in my current project. I did it this way:

A simple anchor that on click event calls a ajax method, this ajax method will call a method in my controller that has a simple call to "create_captcha()" function and then what I return back to the browser is 'image' => $img part and then I just change it in the doom.

Let me know if I explained well.

Cheers!
