Steph, I can't help you with the camera advice since I don't know what is good and what isn't but alot of people here do and can probably help...BUT...if you just want to post pics of Jesse, which we would all LOVE, that is simple...!
You obviously have a computer and I assume it is a decent one (unlike mine!! LOL!!) Take tons of pictures of Jesse and when you get them developed ask for a disc too. Then you can upload pictures to your computer and post them! Walmart will even post your pics for you at their site for like a dollar extra or something...Or most of the stores have a place where you can scan your current regular photos and have them put on disk or emailed to you. Then go to Imagestation or something like that, upload them and then post away!!
I did it for years like that....and since my digital was stolen, I will have to post pics like that in the future too...
I know its hard, you want everyone to "know" Jesse and pics are so helpful....
Save $20 a week and in no time, you will have $$ for a new camera!!
