Need Help

Hello, I am new to this community and I`m don`t understand some things, after you make a work like a business card what form would need to save the work and to upload? I would be very grateful if you explain a little about what must include the folder that you upload a picture jpg or a photoshop format.Sorry if i wrong the topic I`m new

first you design lets say the business card on photoshop then you save it in a folder the folder name shuoukde be labeled like this Your_Name_Business_Card, then you zip it. you make a small png or jpeg thumbnail preview. 80×80 px then you take 2-3 preview pictures which need not to be wider than 900 px zip it use name of the pictures ex 01_Front_Preview than 02_Back_Preview than zip it also and in the end you make the preview on jpeg the one you see when you buy the product where you use the mock ups. then you upload ,,,,.....

Thx I wondered now “then you save it in a folder the folder name” i will save this under PSD format?

well the folder name is your actual name for ex, Sleek_Design_Resume
