No you can't do this.
You can link to it in a tweet or upload the photo on TwitPic.
You can snapshot the photo with your phone and then crop the picture to fit Twitter frames.
Twitter itself only support 140 characters of plain text, so you can't get a photo directly onto it. (except as an avatar or wallpaper)You can post photos 'to Twitter', however, using a third-party service, such as Twitpic, ow.ly, or yfrog - all of which are linked below. Using these services, rather than posting your photo directly to Twitter, posts the photo to the service itself. A link to the service is then posted to Twitter, which can be followed by your followers to see the photo.
when you make your twitter page it asks you do you want to upload a photo.
Save the attachments and upload it to the gallery...
There are many websites that people may want to upload photo's on. Many websites such as Facebook, Twitter, other social media sites offer help and advice on their own sites for those who do not know how to upload a picture.
There are many places to upload photos for free. You can always upload photos to Facebook or Twitter as well as sites such as Photo Bucket, Flickr, and Picture Push.
There's a lot of software and tools to help you do this. The one I use is Photo Party Upload. It lets you share your photos on Facebook, Twitter, Instagram or simply Emailing. They charge per upload but only a few cents. http://www.gcphotobooth.com
Emailing photo is a very simple task in Gmail. You have to click the icon that looks like a pin. Then you have to select the file and upload it.
13unluck: Depending on the phone, you can either send to photo to your email address or directly upload it with the use of a USB cable.
