This method allows the user to set their profile image. The caller can pass image data via image.

Providing a "crop box" with crop_x, crop_y, and crop_w is optional. Otherwise, the whole image will be used. If cropping instructions are not specified and the source image is not square, the image will be letterboxed, just like your favorite old laserdiscs.

Please limit your images to a maximum size of 1024 by 1024 pixels. 512x512 pixels is the minimum.

To remove a profile image, use the companion method users.deletePhoto.

Warning Description

The method was called via a POST request, and recommended practice for the specified Content-Type is to include a charset parameter. However, no charset was present. Specifically, non-form-data content types (e.g. text/plain) are the ones for which charset is recommended.


The method was called via a POST request, and the specified Content-Type is not defined to understand the charset parameter. However, charset was in fact present. Specifically, form-data content types (e.g. multipart/form-data) are the ones for which charset is superfluous.
