How to convert an Image to a string

Hello to everybody.I have a problem.I used a
TypeDescriptor to retrieve a TypeConverter to convert an
Image to a string.The problem is that it converts the
image to the string "System.Drawing .Bitmap" so lately I
can't convert the string to an Image.I've tryed to use an
ImageConverter too,but the result is the same. Why the
converter works like the Image.ToString( ) method?What's
its goal?Anyone know how to convert an Image to a string
so after I can reconvert the string back to the Image?Or
anyone know how to retrieve the name of the file that
rappresents the image?Thaks to everybody.

Wow, there two many concept you need to learn. ToString() normally give you
a string of the "ClassName" . And, what are you going to do when you said
"convert image to string"? Present image binary data with ascII text format?
or, you just want to know the image files' name? Looks you are looking for
the solution for second one, but the fact is, the image data normally won't
carry the file information. The order should be this: you know the file name
first, the you open file to read the image data.
hope this help.

What I want to do is use a web form to upload a TIFF image (scanned images) and convert it to a JPEG before I insert it into SQL Server. The file upload part works great, but I can;t convert the image. I certainly don't want to upload it the the server filesystem, convert...

I have need to convert a text string (with formatting) to an image. This is so that I can resize the image to different sizes and the formatting stays exactly the same regardless of the size. I actually want the font size to increase/decrease as the image grows/shrinks much the way text does in a flash object. Is there an easy way to do this programmatically? It needs to be done behind the scenes on my web site - user enters some text - I...
