Yearbook portraits, if provided by a different photography studio, should be sent to you in an industry-standard PSPA format yearbook export. We can then import those images into the yearbook software for you–just contact us at yearbook.support@strawbridge.net for assistance.
Candid photos should be uploaded to the yearbook software in as high a resolution as possible for best quality print results. The software allows for uploading a number of file formats; please refer to the upload dialog of the program directly for more information.
