Good morning, Val.
You may get more space for attachments if you become a supporting member, but I'm not sure. The better option is to upload your photos to an online web host, and direct link from there. The images come out full size, you can more easily delete what you don't want and they usually have much more storage.
to insert a picture from a web site You can either use the insert image icon that is above the quick reply box (looks like a tree), select the "from url" option, paste the link to the image, and
uncheck the "retrieve remote file" option.
Alternatively, you can copy the url for the image (right click and select copy image location) and insert the link between
tags. The link should look like this (without spaces)
