Hi Milt2016,
I've just begun using WIX to create my own website but keep one important fact in mind: Your website's hosting will always be tied to WIX ONLY. Meaning you will never be able to migrate/transfer the hosting to another entity. If for some reason WIX goes darkside, you will not have a file backup to regenerate your design elsewhere. For this reason I am seeking council from the wise here also.
IS WIX a recommended website/domain hosting entity or is there a better more flexible entity out there one can exploit?
I've already made the mistake of buying a domain from iPage only to realise that it cannot be used on WIX without a WIX Monthly Premium purchased (WHICH already includes a domain & hosting). I feel pretty blonde right now, and have just requested cancelation of my iPage domain account (rather than doubling my expenses). It might delay reacquiring my domain name but I am in no rush.
As for the image quality, take a look at my current creation and see if the images come out better than you expected. I believe it is all down to the res in which they are saved. I assume.
