Just in case somebody thinks it’s GarageSale, it turns out eBay’s image servers are not accepting image uploads this morning in the US. Quite a few complaints on the (typically helpless) eBay Discussion forums.
Just to let you know if you came here to ask if it was just you: Nope.
I was under the impression that uploads of images via GS uses a different system than using eBay’s listing form, sell similar or the eBay app.
I’ve seen image problems and many other problems on eBay’s forums many time before for those using methods other than GS, but these have never prevented me from uploading images with GS. Maybe I’ve just been lucky.
