"no decode delegate for this image format"

[hikari17]

I'm using Paperclip/ImageMagick in a Rails app running on a Windows server.

I get the following error message when trying to upload an image file:

Magick: no decode delegate for this image format '/Tmp/stream,4576,0.jpg[0]'' @ error/constitute.c/ReadImage/532.

Farther down in the error dump, I also get the message:

[paperclip] C:/Program Files/ImageMagick-6.6.4-Q16/identify -format %wx%h 'C:/Tmp/stream,4576,0.jpg[0]'
[paperclip] An error was received while processing... is not recognized by the 'identify' command.

I show the jpg delegate having permission rw-

Any suggestions on what I might be doing wrong?

Thanks,

Dean Richardson

JPG images do NOT support multiple frames. you need to use gif or tiff or some other multiframe format

or if you only have one frame, remove the [0] from the end of the jpg filename

From what I can tell, this command is issued directly by the Paperclip plug-in itself. Is it likely that this is some sort of bug in the plug-in?

Thanks for your input!
