All jpeg images must be at least 4 MP (megapixels), but preferably 5 MP or larger and set at highest quality settings to produce an acceptable file dimensions for submission to Shutterstock.
Please keep in mind that megapixels (MP) are different from megabytes (MB), as they refer to the dimensions and not the file size. To determine the amount of pixels in an image, multiply the pixel width by the pixel length.
For example:
2000 x 2400 pixels = 4.8 Megapixels. A file of this size is acceptable.
1200 x 3000 pixels = 3.6 Megapixels. This is smaller than our minimum size requirement, and this file will not be accepted by our system.
If you believe your jpeg images are at least 4 megapixels, but the Shutterstock upload system says they are not, it is very possible that you are using an image processing software that automatically reduces your image size upon saving it. Please check the settings in your image software and adjust them to save images at 4 MP or higher.
If you are receiving this message when uploading vector files, this means that your EPS and JPEG preview files became separated during upload and your raster file is smaller that the 4 MP requirement.
