Uploaded media is too large


I am getting the following message when I try to post an image:

403:The request is understood, but it has been refused. An accompanying error message will explain why. This code is used when requests are being denied due to update limits (https://support.twitter.com/articles/15364-about-twitter-limits-update-api-dm-and-following).
message - One or more of the uploaded media is too large
code - 193

Unfortunately I can’t find any documentation of image size limits, nor documentation of the 193 error code. The uploaded image is from an 8MP camera.

If I have to downsample, that’s fine, but I want to know what how small it has to be (and not any smaller.)



Bueller? Anyone? Bueller? Is there a documented size limit for image uploads?


I figured out that help/configuration has a photo_size_limit. And knowing is half the battle.
