Hey, I realize this may be a dumb question, but I can't for the life of me figure it out, and it's really bothersome.

So every time I have tried to add an attachment, specifically a photo, I receive an error message that my attachment "exceeds the limit by X KB". Now, I realize there is a 1.91 MB and 800x640 limit on JPGs, but mine is now 400x280 and a whopping 92 KB...and the amount exceeded went up 50 KB more than before I scaled down the image!! Help, please!
