Broken images in Tutorial part 2

[Collin Grady <cgrady@…>]

The images linked to from three of the smaller screenshots are PSDs instead of PNGs

It took me a while to de-encrypt the ticket but tutorials are all png files, don't see where you took .PSD from.

They are Photoshop PSD files but with '.png' extension. Please download them and run unix 'file' utility or open in any text editor:

The fact that "file" says it's a Photoshop Image does not mean it is. File "guesses" file types (read the manpage).
And the fact that the file reads "Photoshop" in the namespace and the CreatorTool attributes does not mean nothing.

This file is an XMP powered file, XMP is some thing invented by Adobe (or W3C?) to add metadata to image files. Inside the XMP file there's the binary data of the embedded file.

Those files were generated from PHotoshop with XMP metadata.

The fact that a linux computer can *view* those images means, simply, that the binary data inside them is not PSD. But I can't assure the format as I don't know XMP.

So, the files are not PSD. You could as "please provide simple png files not embedded in xml" if you wish.

"Simple png files not embedded in xml" were attached to ticket by Collin Grady (please see ticket attachments).

Read PSD file header format somewhere (e.g. "Photoshop File Parsing" section from here ​http://www.codeproject.com/KB/vista/PhotoshopPreviewHandler.aspx) also it might be helpful to read "Embedding XMP Metadata in
Application Files" in official XMP specification (​http://partners.adobe.com/public/developer/en/xmp/sdk/XMPspecification.pdf) I hope this new and interesting information will convince you in "PSD format theory".

You have closed valid ticket anyway.

Replying to dc:

"Simple png files not embedded in xml" were attached to ticket by Collin Grady (please see ticket attachments).

I didn't see the difference between the png's until comment 2.

Thanks for the links, I'll read about XMP later ;)

You have closed valid ticket anyway.

Agree, unless this is intentional (which I doubt) so marking Accepted so somebody can fix that (jacob?)

Changing component to Django Web Site as it's on media.djangoproject.com.
