Suggestions needed for fast upload way for wall art and postcards

[kall3bu]

Yes, I found out, I have to upload a photography, then customize it for EACH SINGLE product and I was successful in doing it for very few test uploads.

I tried to edit a created store and put my posters or so into it, but I could not find the way.

Even if I search for my portfolio: Nothing!

But I sold two postcards last weeks from - I guess - the only photography, which got online SOMEWHERE on Zazzle, but not in my store.

*** Well, my idea now is to upload many of my photography, customize them for posters and postcards only and give the permission to buyers to customize them on products, I did not customize myself. Just to get as fast as possible many photography online.***

Later(!) I might give Zazzle another try for creating a new store, where I hopefully then will be able to post my ready customized things. IF - only IF, I cannot do it afterwards, I would have to find out, what I did wrong last time. But I do not have the time now for studying Zazzle.

I always end up by stop doing anything else on Zazzle, if I try to find out one thing, because it is just to overwhelming. 

Any suggestions, what I can do now to get not frustrated again directly?

Is my idea ***...*** (mentioned above) the best I can do to get just little first success feeling here on Zazzle?

If you answer, please have in mind, I am a 100% beginner without any knowledge about Zazzle.

Thanks a lot for your help.

Puh, finally I found out, where to edit a store, create collections and how I can put my customized products into te collections. 

I never had to bookmark so many sites from one main site, ust to find them faster than searching for them on the site itself.

I did not find a way to delete my first post. But I think, I found my answer myself.
