Dearest Dr. Mike,
I really appreciate your prompt and mostly helpful response but I'm afraid I may have miscommunicated, unintentionally insulted WordPress and irritated you, so please, allow me to explain myself and seek further clarification.
#1 I have read all the FAQs and have been uploading pictures to my blog all along. I just really liked the way the artist's gallery function worked on the Typepad site I provided the link to in my previous message. I wanted to know if I could put thumbnail images in a sidebar widget that would link to the pages where each gallery was stored. It's the sidebar gallery feature I was asking about, not how to upload pictures.
#2 I guess you can't answer until WordPress settles on the number. Is there a way to see my total?
#3 I was referring to downloading the WordPress software and using it on the website that I pay for--not switching to a different blogging software. I have Network Solutions as my webhost because that's what the tech guy at the non-profit I worked for suggested as the most reliable when I was looking for a company to host my site a few years ago. I didn't know they were doing bad stuff on the internet or spamming. That doesn't really make sense, but I'll see if I can find the article on the WordPress.com News about Network Solutions, if that's what you meant for me to pay attention to. Or did you mean that's where there's news about how to download the software and use it from my own hosted site? I've already paid for two years hosting so I won't be changing from them for a while.
