Monday's International iPhoto Day of Action saw hundreds of emails flooding into Apple offices worldwide, according to reports.
Users are complaining that Apple hasn't yet introduced the capacity to order printed photos using the Internet from within the application to its international users. Only customers in the US and Canada enjoy this feature.
Action organizer Simon P reports a steady flow of traffic to the protest Web site. "Many of the requests are now emanating from Germany and other European countries," he confirmed.
Apple has not responded to the protest, but its official line is that: "product marketing are working on it and it will come later in the year".
Simon P says: "Since the service isn't available yet, why doesn't Apple just open up iPhoto to let its international users access services from online print providers they want to use?
"Having to manually upload images to such services takes away one of the main purposes of iPhoto - simplicity and integration."
Apple may not have rushed to make a deal to bring this feature to its worldwide customer base, but it has responded to some criticism.
Part of the complaint was that many of Apple's international pages referenced the feature, even for territories in which it wasn't available.
Apple has now removed such references from the majority of its international Web sites.
Apple stands accused of having a US-centric approach to its customers. One protester said: "Apple gives us wonderful products, but they do seem bad at acknowledging there is a world outside the US." Another wrote: "It is about time Apple listened to its UK customers."
US user sentiment seemingly reflects the US-centric bias the company is currently accused of across the world. A US user wrote: "It is a free download, so what's the problem?"
Simon P responds: "Apple has always spoken of its intention to bring print ordering to the rest of the world. Is it too much for us to remind Apple to get a move on a year later?"
"The international situation with iPhoto is indicative of Apple's continued lack of focus on its international customers. Take Sherlock, which is most certainly not free, but is next to useless for anyone outside the US. Apple promised localized support but has yet to deliver," said Simon.
UK developer Barney Hilken has now released UK Shopping 1.2, a collection of four UK specific Sherlock shopping channels. It took a few weeks to build.
Simon asks: "How hard is it for Apple to do the same?"
Though the day of action is over, Simon hopes more users will contact the company to encourage it to overcome its apparent US-centric bias.
"Tell Apple what you think," he said.
Macworld is hosting a special forum debate on the matter, called Is Apple US-centric?.
