Yesterday I downloaded several vector images, and while most of them were great, a few were low res and I could not get any high-res version to download, no matter what I tried.
The image numbers are: 66656829, 91281715, and 92799497.
I'm wondering if I can just get my credits returned for these so I can replace them with high-res vectors I can use.
Vectors don't have a resolution you should be able resize them infinitely without losing quality. Can you take some screenshots of what you are seeing??
