This is SO frustrating. Save for a few people here and there I use Talk for all of my texting/IM'ing needs. It's quite frustrating when I have to open an SMS/MMS app on my phone just to send an image mid-conversation. Other IM clients added this functionality very early on in their lifespan so it seems to me that the ability to send images over Talk is LONG overdue. What is the holdup on this? Can we expect this anytime before the end of the Android/Google run? Does it open security vulnerabilities or create stability issues? Anyone know anything about this?
