Store banners are resized by Zazzle to 2048 x 565 and then are scaled to fit the viewing device so it is a good idea to keep important elements near the center as the outer edges may be cut off on some screens, particularly the right edge. Also try to avoid putting anything in the lower left 1/3 area as that gets covered by your profile pic block and title/desciption that Zazzle adds. Something that may be sort-of close to that area on one screen may actually be getting overlapped by it on another. The minimum allowed size is 1140 x 315.
Your Profile Pic that is overlayed on your store banner needs to be a minimum of 512 x 512 but it is displayed at 150 x 150.
Profile banners get sized to the same size as Store banners (2048 x 565) but in their case, it’s the very center you want to avoid decorating on as that’s where your profile pic and name & description are placed by Zazzle. The minimum allowed size is 1140 x 315.
Category cover images have no minimum required size but they are displayed st 253 x 253. Making them larger is just a waste as they aren’t going to be displayed that big. Also, “window” style cover images that show a variety of the products in that category may look good at say 1280 x 1280 when you are creating them but when shrunk down to the display size of 253 x 253 the detail one might have been aiming for might not be as clear. Not to say there aren’t a lot of great looking “windows” out there - there are - just keep in mind if you go that route it’s only going to be seen at 253 x 253 not whatever larger size you design it at.
Collection Cover images need to be a minimum of 324 x 324 but are displayed at only 272 x 272. (If instead of adding a cover image you just let it show the first item in the collection, it displays at 252 x 252.)
Collection banners are 1140 x 315.
Media Files (the “Media Items” they want you to add at least ten of to your store Home) need to be a minimum of 1440 x 1080. See this post (11/13/2020) for more information on the Media section.

TIP: If you forget what size an image should be try using one you know is very small and you’ll get a message on screen telling you that your image is too small and the minimum required size. (Except for Category covers, for some reason you don’t get such helpful info when trying to add those.)
