For everyones information, me and a few others have managed to upload pictures.
Here's how I uploaded 10.
Reduced resolution to 1920*xxxx (ended up being 1280 to keep scale) and max file size of 500 KB.
I uploaded the pictures to "Concept photos" because it was the only available picture uploading location.
With the original picture size, I wasn't able to upload more than 4 even if the files themselves were 800-900 KB.
Also, as in the rules, don't forget one hand written username picture with date along with a picture of the Gigabyte hardware because you need to have both Gigabyte Motherboard and GPU(s).
