This has been happening for... perhaps for years.
I have an image gallery here http://windwanderer.com/image
When I load any page of this gallery, only SOME of the thumbnails are loaded and the rest show the default text.
Which thumbnails load and which do not changes with each load. Try it, go to the link above and see which images are shown (you may need to scroll down) then click "reload" on your browser. Some of those that looked to be unavailable will be loaded and some of those that loaded correctly the first time will now appear as thought the image can't be found.
The error occurs in Firefox, Midori, and even Dolphin browser running on Android phone!! Haven't tested it with iexplorer.
I believe this problem may have persisted over an upgrade from Drupal 5.x to 6.x
My guess was that it had something to do with the cache. Here is what I have done:
- I've emptied it
- turned off page caching
- rebuilt the derivative images multiple times
... yet the problem persists.
I would really appreciate any help. Please be patient, though, as I don't sit at my computer every day and it may take me time to test solutions.
