I had a thread talking about some of my directional challenges recently too... each project has a different set of decisions to make!
Our help section here has some good FAQS on pictures:

It took me months to figure out the challenges of my older digital camera and browser choice, and found that for me the big issue is that the file sizes are too large. I go to this site, use their defaults and I'm good to go. No affiliation, but it is easy and doesn't set off my protection settings.

And then, once you do get your pictures attached, about half the time I forget to resize the window to where I can see the "upload" button in the far right corner that has to be clicked in order to actually attach everything together... No pressure, but there is a time limit too.
