Drew, i'm an older guy and figured it out twice, so you'll be fine, although you may experience moments of frustration until you figure out the process through some trial and error. I have used both photobucket and flikr to upload photos and then share them here, so it's a 2 step process. The tutorials linked above will help. For this go-round (i just started posting again after a multi-year absence) i am using the flikr app on my cell phone and taking pictures with the phone cam--easy and convenient. You then send the photos from your phone to the hosting site, in my case the flikr app. You can simultanteously access your flikr file and the forum on a regular computer also, and do the same upload. I also use my e-reader (Nook - Samsung Galaxy S2) to do this. For me, the process is slightly different depending on the quirks of the particular device, so you have to just try things to see what works. After some brief frustration, you will figure it out. If i can do it, you should have no problem. If you encounter difficulty, there are lots of folks here who are smarter and more tech-savvy than me, and they will be glad to help upon request.
Best,
Bob
