Thumbnail always blurry

[JoanCB]

Hello, 

No matter what I do, raster or vector, my thumbnail image always looks blurry and unprofessional. I used Zazzle’s recommendation, but it’s still terrible. Does anyone have a solution for this problem?

Thanks!

@JoanCB  There's nothing you can do. Zazzle resizes them for optimization and we just have to accept the quality

Make sure they are 1480x1480 resolution. If they are any other size they will look blurry.
