Mark, I'm a dinosaur..Engine gerabox diff and suspension guy, not a clicky-cliack nerd boy..I was taught how to post piccies by a very kind and patient Canajian guy I was building a gravel Sierra for..Do this..
Do you have your piccies scanned? So they're somewhere stored on your confuser..OK
Are they "hosted" on some photo hosting service???
IF they're "hosted" (sitting) on some serive, you go there and click on the piccie, like here's my Canajuan friends 'build journal" with the local (my) made versions of Ford's Group N rally struts...
When that pccie is open look up in the "address bar" and you'll see an address looking like
To put the piccie here you "left click and hold it down and swipe over the address and either type Ctrl and C or right-click and in the drop down menu choose "Copy".
Then where you want to post the photo you can either look just above this screen at the 3rd symbol from the right..and click it
A box pups up and you hit "Ctrl" (lowest left on the keyboard) and V
Then hit OK and POOF!
Opps maybe I should have said when the photo is displayed at the Host site you "right click" and hit "copy image address"
and put that in the box OR you can type
