Actually it can be helped aside from getting a 3rd party messaging app.
Attach your image to a text message, turning it into an MMS, and send it just the image with no text accompanied. Then immediately after send your text in a regular SMS message. Now when you open the image, it will open in a Gallery type app as just an image, and not a slideshow.
You could of course get a 3rd party app, but my preference personally is to use stock firmware as much as possible. No point in doubling up on apps that achieve the same purpose.
