How to upsize a picture in PS4

HI! I am trying to get a few photos ready to submit to a stock agency. In reading their requirements, they need to be at least 24mb in size. I have a few that are not. How can I upsize these? Right now the size I am looking at is in Bridge and in raw. I took them in my studio.

  Hi Rhonda,
My Canon 5D mk II shoots raw files at 22MB range but when I convert this image to an uncompressed .tif file - it gets bigger (60+ MB). Try converting them again and save as uncompressed .tif and you should be good to go. I also shoot at 16 bit depth which translates to 120MB .tif but usually I change the image back to 8 bit to save space on my Hard Drives.
You can also Cntrl+I (Image size) and increase the pixels but this is not preferred and increasing too much will degrade the image quality.
my .02,

doug Nelson   Could it be that the stock agency wants high-bit (over the 8 bit per red/green/blue channel) images, so that THEY can do any color and tonal correction? I have heard of agencies asking for the RAW image in the camera's proprietary format. Photogs (like me) who convert my RAWs to DNG could come up short. But, I don't sell anything, anyway.

  The Tiff image for sure works. But they are asking for a high quality JPEG. Once I convert to JPEG - it is tiny in size. so I have no idea what to do next.

  Rhonda, that's definitely a large JPG image. My camera has a pixel resolution of 5616 x 3744, and saved as a JPG at max quality results in file 12MB or so.
