HTC Droid Eris :: Automatically Resizing Photos For MMS

First time trying to send a photo via text message (MMS). On any number of my previous phones, the phone would automatically resize the image so that it wasnt too large to send. That does not appear to be happening on the Eris. I sent one photo, and it was nearly 1100kb. Then another photo I attempted to send would not attach, because it said it was too large (it was like 1250kb in size). So, is there a way to have it automatically resize a photo that is being sent via MMS? Or will I need to do that manually beforehand with an app from the Market, like Picasa or something of the sort?
