( #3333=superdoc: print w/replies, xml ) Need Help??

I've played around with something like this before, and indeed I think it's pretty cool, and can be done with any image. The one big downside is that the "size" of the image, in terms of downloading it, is much larger than the image you're replacing. With a gzip enabled server, that might not be so bad however.

On the other hand, although this is a cool hack, I really hope it doesn't catch on. I usually browse the web with images off so I can skip the annoying advertisements that represent probably 80% of web images nowadays. With this technique, there's no good way to turn it off except to disabled displaying divs. And that would probably be a nightmare. I could see unscrupulous advertisers using this technique to get around image blocking and such.

PS. For some fun playing around with this for any random image, download bmp2html. You can modify the source to spit out colored divs, like your program does, instead of colored ASCII characters.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
