If you want to convert an image into a text just for fun , I have found two sites that you can use. If you see something like you see in screen shots I have used in this post and you also want to do the same, you can use these sites.
You can easily generate cool text images from almost any picture you have in your computer. After converting you can copy the text on a notepad application. It is not so much useful if you copy and paste in on notepad. So for picture you can convert into text.
It is good choice if you want to convert an image that has a text you can convert it to real text.
