First, emailing your artwork for t-shirt printing directly to admin@yque.com is the best way to upload your artwork. This is an open ftp interface, but it is not a guaranteed way to transfer the your t shirt artwork files. Emailing artwork as an attachment is a full-proof way and private method of sending files. Please reference your order or quote in the subject line of the email. If you can't email the file then you may want to try this upload interface.
Each file must have a unique name. Please name your file something identifiable for the artwork so that I can place each file with your specific quote/order.
If you are having an problems with this upload interface you can email me the artwork to admin@yque.com or call Bill at 213-308-2269. You can check by going to this folder and clicking on the file name, then seeing if it downloads properly to your system.
