luckymothers review for creativehub: Sell Art Prints

Jeeezzzz.Uploading files is a joke. Out of 40 .png files approx 6 were vieweable after 3 days. Supports answer was basically dont use .png though they advertise it is a supported format.. Currently looking at 3 dozen + un-viewable/un-usable files i need to print. This is Creativehub not Shopify.
