I need help to size photographs to 4X6. I have done this in the image size but now that I am trying to submit them via online ordering they are being cropped down to tiny thumbnails. HELP!
Use the crop tool
Enter W&H, resolution 300 px/in, on the crop tool's option bar
Drag out the crop box to embrace that which you wish to retain, then crop.
Save as JPEG file
Upload to online vendor.
