Hi Peter, regarding uploading pictures, it helps if we know what operating you are using. On Apple iPad, I find that if I use the attachment button under the text editing, Apple gives me the option of small, medium or large with the respective file sizes.
The forum limit is 1 Mb per attachment, but in practice around 200 kB is quite satisfactory, and so preferred. So select the appropriate size and select “use”.
If you are using Windows, you need to resize the pictures to about the same size range.
There are methods using external hosting that many members prefer in order to insert photos in the text, and you will get to know how to use these as you get more familiar with how the forum operates.
Hope this helps,
