Hello thefishermanfl.
I understand you are unable to print from the Photo tray using your Photosmart 7525. What is your operating system on your computer? Windows or Mac?
If you have a Windows computer please follow this HP document on Print Photos Saved on Your Computer.
The crucial step to perform when printing on special media paper is changing the settings within the program you are printing from. Make sure you change the Paper Source to "Photo Tray", so it grabs your photo paper.
Please inform me your troubleshooting steps.
Looking forward to hear from you.
