While customizing your crystal on the product page, click on the 'Upload Photo' button. A window will open, allowing you to browse through images stored on your device. (It is the same process as uploading a picture to your email) You can upload up to three (3) pictures and ask the designers to choose the best fitted one, in the Special Instructions Box. This section will also allow you to crop your image.
We recommend uploading files between 100kb and 5MB for the best picture quality. Our website has a size limit of 5MB so if you would like to upload a photo larger than 5MB, please send it as an email attachment to firstname.lastname@example.org
In regards to your crop, try and avoid having sharp crops on your images. For example a “selfie” with half a face cut off. Being that if this kind of image is provided, that is how we will engrave the image. Our designers do not recreate images. We simply edit the colors accordingly to be able to be etched on the crystals.
