Working OK with Mac browsers, not PC browsers

[lolsen]

Please help me troubleshoot this problem. I can't seem to find any rhyme or reason to what's happening.

Here's the gallery in question:
http://northwestcellars.com/winelabels/index.php

In some browsers (Mac - Firefox and Safari), ALL of the thumbnails, intermediate and large size images show up perfectly. Coppermine works as expected.

On PC browsers, images are missing in a very inconsistent manner. Depending on which version of Firefox - 3.0.1 is about 98% OK - but in earlier versions, most or some thumbnails, and most or some intermediates are missing. I haven't checked on the large images. (If users can't see thumbs or intermediates, who will have the patience to click further?)

Testing on IE 6, 7 and 8, the results are even worse. Out of 12 thumbnails on a page, if lucky, about half will show. Sometimes only one.

Since ALL images are showing up on all Mac browsers I've tested, then I can assume that the image files and database are both intact. Still, I did rebuild the thumbnails thru Admin and there was no change over on the PC side.

Upgraded from v1.4.18 to v1.4.19 - no change

I've also switched on and off hotlink protection, per a suggestion on another post, and while some images did show up, it was only about 60% successful.

Other details that you may find useful:
- All images were added via batch add process, admin only, no other users
- This is being used as a client-only photo album, so no user registrations
- Default mode for directories: 777
- Default mode for files: 666
- I have modified the template.html and CSS to fit my client's branding, but experience the same error on standard themes as well.
- Shared web hosting
- Apache version: 1.3.39 (Unix)
- PHP version: 5.2.5
- MySQL version: 5.0.51a-community
- Operating system: Linux

It would seem that it's more likely that there is either a CPG or server setting that's causing this, rather than browser idiosyncrasies.

Appreciate your expertise! :-)

Here is an array of screenshots on browsershots.org that illustrate the problem:

Do you verify by yourself or only with browsershots.org ?
Because, my visit on your Gallery is fully perfect, no issue at all  (FF3.01, Op, IE7)

No, not by browsershots.org solely. I have an offline bare-bones PC (WinXP, Firefox 3.0.1, IE7) that I do some testing with. Since there's not much on it, I tend to get a rosy view of the world.    When I go live, I use browsershots to look back a version or two to see what the rest of the world might be seeing.

A week ago, my client said that images were missing in Ffox and IE, but everything is there today. I ran another group thru browsershots to double check, which are the links in my post.

So... I'm not sure which change I made fixed the problem. Just want to ensure that my client's gallery will be operational.

Thanks for your time!

Browsershots will definitely not give the expected results, don't trust it. Use a real Windows box to perform the tests. Post deep links and exact OS and browser information. Make sure you're not only running into timouts or local caching issues by pressing force-refresh in your browser. Also make sure that there are no third-party factors (like proxies, pseudo-security-apps, ad blockers or similar interfering. Also review your use of add-ons in FF3.
Browsing your gallery worked fine for me using Ubuntu Linux and Firefox 2.

Looking into the deep links your posted shows that some of your images are corrupted: when accessing http://www.northwestcellars.com/winelabels/albums/uploads/806020_MIHS_FINAL.jpg (the pic behind http://northwestcellars.com/winelabels/displayimage.php?pos=-416) I get

Die Grafik "http://www.northwestcellars.com/winelabels/albums/uploads/806020_MIHS_FINAL.jpg" kann nicht angezeigt werden, weil sie Fehler enthält.

, which is an error message of my browser (FF2) in German and means "The image "http://www.northwestcellars.com/winelabels/albums/uploads/806020_MIHS_FINAL.jpg" can't be displayed because it contains errors". In other words: your actual images are broken. Some browsers may be able to fix this on their own and display them properly, others won't be capable to do so and will result in a message similar to the one I reported. Instead of looking into several browsers, find out why your images are broken. I was able to download the above sample image to my PC and view it there using the OS's image viewer and theGimp. According to the properties of that image it is RBG (which is fine) and has been created with Adobe Photoshop CS2 Macintosh, so nothing wrong with that. I don't have the tools available here to start an analysis what exactly is wrong with that image for my browser, and I am by no means a Mac-specialist, but I'm pretty sure that this is related to some Mac-specific things that PC operating systems don't "like".

It's actually CMYK. You need to save it as RGB.
