I just send all my phone pics straight to Photobucket(there is a Photobucket app if you don't have it yet), then in there you can get the links to copy and paste into the forum.
Do you know how to upload multiple photos at a time to Photobucket? If not, when you're in the gallery, hold your finger over one of the pictures for a second or two, then it will get a check mark on it, and you can check more pictures too in the same album, choose hit share > Photobucket.
These things have a steep learning curve when you first get them, but once you get used to it you'll wonder how the hell you lived without it!
Not to derail it, but check out the following apps(all free), good to have for car related stuff:
-Bubble(it's a programmable angle finder)
-Realcalculator(scientific calculator)
-Droidlight(uses the LED flash on the phone as a flashlight)
-AK Notepad(generic notepad... great for writing notes for various stuff down)
-Convertpad(conversions for ANY unit of measurement, it's awesome)
-aCar(keeps track of MPG and service records and cost vs time, etc... it's pretty handy)
