You can purchase the images directly via cell phone or computer and then transfer them to your cell phone.
To purchase any image, become a member or post comments, you must first register in the store. This registration can be used in the future to create your own online store for free, if you wish.
Once you have registered and are already logged into your store account, you can download the free images or purchase paid ones, choosing the ones you like best and adding them to your shopping cart. At the end of the purchase, the download link will be displayed and an email will also be sent to you with this same link.
After downloading the ZIP file, unzip it to your library to extract the JPG or PNG images. Then simply configure your cell phone to display the image as the background screen, whether on the lock screen, the applications screen or both, including using different images on each of these screens.
If you make the purchase on your computer, there are several ways to transfer the uncompressed images to your cell phone, the easiest being using WhatsApp (if you have it on both devices, cell phone and computer) or sending them by email to yourself.
