Right... mum has been moaning about her images so time so here is a quick solution, its not neat but there are good reasons for this.

1. Upload your images as normal with googles picture tool.
2. Goto Edit HTML
3. Find the URL for each of the images and copy them down to word or something. They will be in speach marks
4. Delete all the HTML about your uploaded image.
5. Type;
img src="the URL for that image" /
and put it inside triangular brackets, I haven't so Google actually shows the code.

Repeat for all your images, and put in a br inside triangular brackets every time yo want a new line.

Unfortunatly this will not display your images in the neat little small medium or large, options but at full size so either save images smaller, or continue with the columns.

My excuses for this not being perfect, is that a) Google uses a different language called PHP to do the images and it only lets you edit basic html and removes PHP code.
b) Googles HTML edit is rubbish and is filtered to prevent hackers.

The geeky Hallett.
