Bug: Upload script does not generate image sizes of PNG image attachments

Upload does retrieve the image sizes of GIF and JPEG images, but not of PNG images.

Test case

Attach a PNG image and select "Create a link to the attached file at the end of the topic". Look in the source. You will notice that text below the attachment if pushed down as the image is loaded.
