I do custom metal fab, too! Small world.
If you have an iPhone download the free PhotoBucket app. Upload your pics to the app (I can teach you how) it's really easy. But first you have to download the free app and setup your acount, which is also free.
Then you open the PB app. Click on the "Upload Media" button on the bottom of the screen. Then at the top it will have 2 blue buttons "Choose Existing" and "Choose Camera". If you have them saved on your phone, click on "choose existing". Then choose where they're stored like "Camera Roll". Then choose which album. Then choose the picture and it will start uploading. Then when you click on the picture once it shows up in your photobucket library. You click on the IMG code and post it in the reply box. Then hit reply and you will post a pic.
It sounds complicated because I'm being thorough, but it gets really easy, fast.
Also, if you use the IMG code, it will never tell you it is too large or anything like that.
You just paste it in the reply box, like you would a website.
