Not only do I sometimes have problems e-mailing sellers who are foreign (from my perspective), getting the "We're sorry we couldn't find an answer for you. Unfortunately, this seller is not able to respond to your question. We suggest reviewing the item again to see if your answer is in the seller's listing." message; but a foreign buyer also alerted me to the fact that they couldn't e-mail me and I do ship internationally.
One can circumvent it by e-mailing sellers directly as opposed to e-mailing them from the item page, but 1) this is annoying and 2) not everyone knows how to do this or can be bothered doing this, which means a decrease in potential sales in the later above scenario.
Someone needs to figure this shit out.
Regarding the mis-match of item thumbnails under the messaging system, this minor bug is not due to the above user's web browser settings but does, in fact, exist.
Regarding eBay's photo-hosting or to be more precise, the automatic downscaling/downsizing of uploaded photos, this is in fact, pretty damn retarded. It used to be that the free gallery photo was self-hosted (assuming you self-hosted it and gave a photo URL as opposed to uploading the photo itself to eBay), but now all free gallery photos are hosted on eBay. There is actually a legitimate reason for this, but the automatic downgrading of photo resolution and size makes it way too small.
What the hell is eBay doing? It's like they want to fail. The faulty messaging system results in less sales and thus, less FVF for eBay. The low quality eBay-hosted photos may result in less sales and thus, less FVF for eBay. eBay rarely makes changes that are positive for sellers as well as buyers, but now eBay are implementing changes that are negative to even themselves!?
I can't remember the last positive change eBay has implemented. It's just a long line of bad or at best, questionable, changes.
