    I am having problems w/ the site getting stuck trying to load some icons and pictures. Jon J mentioned something yesterday-maybe the same thing. Usually I can sign in OK, but after looking at something and then going back, the light bulbs dont come back up (and maybe other stuff too).

    I’ve got a lead on what the problem might be and will be working on it. Thanks for the head’s up guys. I was able to make the problem happen on this end too. It is very intermittent and it goes away if you close out your browser and open a new session with Internet Explorer.

    I’ll holler when I know more and appreciate you guys taking the time to point it out.

    Browser Problems Caused by Photoshop 7 JPEG images

    We would like to alert our users to a problem caused for Web browsers and other applications by certain JPEG files created with Photoshop 7.

    With PS 7, Adobe decided by default to embed XML-encoded “preview” data into JPEG files, using a feature of the JPEG format that permits embedding of arbitrarily-named “profiles”. In theory, these files are valid according to the JPEG specifications. However they break many applications, including Quark and, significantly, various versions of Internet Explorer on various platforms.

    The symptom in Internet Explorer is that the browser becomes “stuck” in downloading an image file, and its memory utilization starts to increase at the rate of about 100K per minute. After this occurs, the browser can still navigate, but it will not display any images at all — neither offending PS 7 JPEG images nor any other kind of images, on photo.net or any other site. People have noticed this behaviour and tend to blame it on photo.net, since they don’t encounter it on other sites. This is only because other sites have more control over the images that are included on the site, whereas photo.net currently accepts all JPEG files.

    Once the browser is blasted by one of these JPEG image bombs, one can recover on some platforms by closing all browser windows and restarting the browser. On some platforms, it is reported that it is necessary to reboot the entire system.

    We have searched the Microsoft web site for Internet Explorer workarounds or patches for this problem, and we have not been able to find any. IE 5 and 6 on Windows 2K, and IE 6 on Windows XP are some of the version/platform combinations that are impacted, but there are likely others.

    On Adobe’s web site, various workarounds given include using the “Save for Web…” function to write the JPEG file, or to set Preferences to disable the saving of “preview” data in output files. Since these workarounds require action on the part of the Photoshop 7 user, photo.net is currently at the mercy of any PS 7 user who does not know about this problem or ignores it.

    We are therefore working urgently on a way to filter out these JPEG images. In the meanwhile, we appeal to our users not to upload JPEG images created in PS7 unless they have been saved using the “Save for Web…” feature.

    I’ll just screen the images uploaded looking for any of these images created in PS 7 and just replace them. Not a huge hassle, I’m on the track of a permanent fix to be put in place on this end that will solve the issue.

    Just thought you guys might want to know what is / was the problem. One thumbnail saved ONE way in a particular piece of software caused all this fuss.

    Easy fix…

    1.) Use jpegtran to Patch the Adobe Photoshop/ImageMagick bug

    When users save images in Photoshop 7.0 as jpegs, then upload them to a PhotoPost powered site that uses ImageMagick, the resulting resized images are sometimes corrupted (and once viewed in a user’s browser, these corrupt images cause image display problems in IE across all web sites during the user’s browsing session). This is because Photoshop embeds incompatable XML data into jpeg images. We’ve added support to the latest PhotoPost versions (3.3 and newer) for a utility called jpegtran, which strips out the XML data from image uploads before ImageMagick resizes the image.

    I’ll get this taken care of over the next 24 hours so nobody has to worry about the software they use to save their images.

    And a peaceful calm and harmony lasting a century returned to the villagers.

    Oh sure, blame it on the red head. I guess that’s what I get for using a Mac. Oh well, I guess I’ll have to take my lumps and like it.

    James, if you want me to save my images differently, let me know and I can do so.

    That really hurts coming from a Perch jerker. I’ve got a really sharp stick, would you like to bury that in my eye too?

    That’s ok Herb, I know where you live.

    Photoshop 7 does have a lot of new advances over 6. I never gave it a thought as to how to save my pics. There is a ‘Save for Web’ feature in 7 that would probably have prevented this problem. Like I said, I never gave it a thought. I work with Photoshop 7 all day at my job scanning photos and alike. It is a GREAT program for web graphics and photos. That is not to say Photoshop 6 isn’t, but 7 has more features geared toward web applications.

    Somebody had to be the guinea pig, I guess it was my turn. Now we know and I’m sure beyond a shadow of a doubt that James will have it fixed right, quick, and in a hurry.

    Bill, if by chance you do get Photoshop 7, and have any questions shoot me a PM and I’ll see if I can answer them. For that matter, if you ever need help with 6, let me know and I’ll see what I can do.
