Image too large when posted via XMLRPC

Hey WordPress Warriors,

When I upload an image from Classdroid to WordPress via the XMLRPC plugin the image is too large in the interface. If the image is say 1400px wide it will attempt to show a 1400px wide image.

What I want to do is have WordPress understand that an intent for an image has been passed and create a second image (almost like a thumbnail) that is suitable width for the post.

Any recommendations on best practice here? Is this something that is already supported and I’m just missing a trick?

I’d much rather handle this in WordPress than on the client app.
