HTC One M7 :: Change MMS Sending Size

When sending an MMS (in my most recent example, a screenshot), it reduced the size of the image drastically, almost to the point where the text (the reason I was sending someone a screen) was unreadable.

Is there an option to disable/change the resizing (or by how much) of pictures when sent by MMS?

Now, there IS one option that allows you to change the outbound max size of an MMS under Messages-->Settings-->MMS Settings--> Maximum Message Size. This gives 3 options, the largest being 2MB, which I have it set at. That said, this doesn't seem to impact the re-sizing of pictures (or, alternatively, how large they can be) as the phone shrunk my screenshot down to 46k and 360x640.
